Care, Cleaning & Sportsmanship
Chapter Four
MOLY COATING
The first half of this
book was written over a year ago. It was supposed to be ready for Camp Perry in
Aug. 1997; I'm so glad it wasn't. In the past month and a half, I've learned so
much that makes the old methods of care and cleaning obsolete*.
*Special note; during
the editing process, Charlie took exception to a few of my comments and thought
they needed expanding upon. Charlie says, "Doesn't make other methods obsolete -
not everyone is using or will use moly. Use of moly will determine cleaning
method needed, much the same as the different barrels and loads will affect
cleaning methods and materials. These other methods aren't old and are needed to
correctly care for equipment which is being used with industry standard match
projectiles and conventional bore surfaces."
My Learning Process
I think the best way to
approach this is to give it to you in a sort of chronological order as I have
learned it.
Over the past year or
so I kept hearing these words, like whispers on the wind; Moly, Moly Coating,
Molyed Bullets, Moly, Moly, Moly,
Moly.
I saw my first Moly
coated bullet at
Camp Perry.
Thomas Whittaker had just won the National Championships. The next day, I was
two targets down from him during the team match. The bullets were a purplish
color and very shiny. So then I knew what they looked like, but that was all.
At Camp Perry I was
introduced to Dave Emary, Chief Ballistics Scientist at Hornady Bullets® . Dave
told me some interesting things about Moly coated bullets and what they can do
for you. I will be referring back to our conversation because as you learn the
wonderful properties of Moly coating from other credible sources, Dave's
experiences gain a great deal of credibility, but more importantly, become
additional confirmation.
At Camp Perry I
interviewed 6 National Champions, asking them how they cleaned their barrels.
Naturally, I got six different answers. The first half of David Tubbs answer
opened my eyes (The full answer will be given later). "You know I Moly? I do not
have to clean my barrel for 150 to 200 rounds" (Without a loss of accuracy).
That was almost
identical to what Dave Emary had told me a few days before. "You can go through
a match like Camp Perry
without cleaning the bore or with just a very light cleaning." (Over-cleaning
has a negative effect).
Walt Berger from BERGER
BULLETS® told me: "Bench rest shooters normally clean the bore after every seven
or eight rounds. With the Moly coated rounds, I'm cleaning after every eighty or
one hundred rounds with no loss of accuracy, and you know how important accuracy
is to us."
Dave does not recommend
this for everyone, but he has tested up to 250 rounds without cleaning the bore,
with no loss of accuracy. There is an unconfirmed story of one shooter firing up
to 1,000 rounds of Moly coated bullets without cleaning the bore and with no
loss of accuracy. Later I will show you WHY this can occur.
In the past I've
learned that the advocates of Moly coating are claiming five wonderful things:
1) Longer barrel life, 2) Improved accuracy, 3) First shot accuracy, no fouling
shots, 4) Longer times between cleaning with no loss of accuracy and 5) Cleaning
of the bore is by far faster and easier.
Anything that sounds
too good to be true usually is. NOW, I'M INTERESTED and I want to learn and find
out, ARE THESE CLAIMS TRUE? I have heard people say "Don't say that (1-2-3-4 or
5). That hasn't been proven yet!"
As far as I'm concerned
ALL FIVE CLAIMS ARE TRUE. I will attempt to share the best proof I have. I think
we covered number four already. I'm not about to argue with David Tubb, Walt
Berger and Hornady Ballistics Lab.
Let's take the
remaining four claims: 1) Longer Barrel Life. Dave Emary from Hornady says he
does not believe the claims of 2 to 3 times longer barrel life. He thinks it's
maybe 25 - 30%. In my book 25% is a significant amount, and well worth the
effort to moly.
Now let's look at the
other end of that stick. Uncle Bob works for a large gun manufacturer and he
says in their test with molyed bullets they are getting (with some barrels) 2 -
3 times less throat erosion. He says this is caliber dependent. The .223 caliber
is by far the best, the .30 caliber barrels have a significant increase and the
belted magnums have a slight increase in barrel life. The test showed the best
results came from cryo treated, high quality barrels.
Locally, Dave Hickey is
our resident expert on the AR-15 and he keeps excellent records. He says that
during the 1992 shooting season, before he molyed his bullets, he was firing 52
gr. bullets at 200 yards, 69 gr. at 300 yards and 80 gr. at 600 yards. Over a
period of 3357 rounds he was getting about 61 rounds per one thousandth of an
inch throat erosion.
In 1997, using molyed
bullets, he started with a new barrel; same type, same caliber, same chamber,
same barrel maker, same gunsmith and same powder (ww 748). He used only 69 gr.
bullets for 2 & 3 hundred yards and 80 gr. for 600 yards. In 1,031 rounds, he
was getting about 208 rounds per one thousandth of an inch throat erosion. 208
divided by 61 is 3.4. OK, you decide: 25% on the small end or 3.4 times less
throat erosion on the high side. In either case, I think it is worth the time
and effort.
Now let's talk about
claim number 2): Improved Accuracy. Back to the conversation with Dave Emary in
the pits at Camp Perry.
He said, "You will notice your groups will be more round, with fewer fliers and
possibly tighter." (Note, you have to do your job for the molyed bullets to do
their job. Throwing your shoulder into the rifle, mis-aligning the sights or
jerking the trigger will not help).
Boots Obermeyer has a
6.5 mm barrel with about 4,500 rounds on it. He started to shoot molyed bullets,
and won a 4-gun 600 match at Eau Claire, Wisconsin this summer with a score of
798 out of the possible 800. Big Deal, he'd done that plenty of times. BUT, his
X count this time was 63 X's. He says his groups are rounder and smaller.
I just started shooting
the Hornady 75 gr. A-Max® bullets, molyed. I shot a 4-gun 600 match. The first
two strings were with Iron Sights and I had a lot of elevation problems. The
third string was with the scope and I had a 200-9X. Big Deal, BUT, I noticed in
my data book, all the shots outside the X ring were JUST out. If the X ring had
been another inch to an inch and a half, I would have had a 200 with 17 X's. I
know, if a frog had wings, he wouldn't bump his butt everytime he jumped.
A couple of our
Expert-class shooters have found their accuracy is better with the molyed
bullets. They are getting 200's at 600 yards and 100 with 5 X's at 300 rapid.
They are happy.
Point 3): First shot
accuracy, no fouling shots. Grant Ubl is on the Wisconsin Eagle Team (They won
the Civilian Combat Infantry Trophy Match at Camp Perry in 1995 and 1996, missed
1997 by a few points and won again in 1998). He is also high in the running for
the 1998 U.S. Palma Team. In other words, a damn good long range shooter.
Grant has been shooting
Molyed bullets for over a year now and he wanted to see how his first shot
accuracy was at long range. He just finished a Palma Match and had about sixty
rounds down the bore. He used his cleaning method (covered later) and the next
day fired a Thousand Yard Match. His first shot was right where he finished the
day before, just above the X-ring. His second shot was right through the spotter
and the next three shots were in the same spot.
Police (SWAT Teams)
MUST have the first shot right on the money; they don't get sighting or fouling
shots. They call it their "Cold Bore Zero." I believe that eventually the Police
will be using the Molyed bullets for this point alone.
George Lainhart is a
SWAT/Sniper Instructor on the City of College Park Police Department in College
Park, Ga. He says with the Molyed bullets his "Cold Bore Zero" is on each and
every time. He says that Bert Medina, the Chief Firearms Instructor for the U.S.
Customs Agency, is using Moly coated bullets. George says that Norma and
Blackhills Ammunition Companies are producing Moly bullets for the Police. If
you are a Police officer and would like a fellow officer's views, give George a
call at 770-964-7028.
We have already covered
point 4): Longer times between cleaning with no loss of accuracy. So let's move
on to point 5): Cleaning of the bore is far faster and easier. That is the point
of this book and it will be covered as we go along, and after learning some
fundamentals.
The next large step in
my education came in the fall of 1997 when I saw an ad in Shooting Sports USA
for a product called Ms. Moly® , Ballistic Conditioner, an aerosol spray Moly
(1-800-264-4140, for technical support or questions call 414-763-8687). I
noticed the company was in Burlington,
Wisconsin about a forty-five minute drive from me, so I called and talked to
Dave Brown, the man in charge. Dave invited me down and gave me a complete run
through on both Moly in general and his product in particular.
I didn't know Dave
Brown, so I was skeptical. He had two things in his favor. The first and most
important thing he had going was a booklet from Dow Corning® called "Illustrated
Mechanism of Molybdenum Disulfide Lubrication." This is a series of pictures
taken under an electron microscope. The second thing he had going for him was
the fact that he demonstrated his product and it did what he said it would. Both
convinced me that molying both the bullet and the bore is absolutely the way to
go. His product has a better way to do this (in some respects) than powered moly.
Before we get started
lets get a few things straight. We are talking about Molybdenum Disulfide. I'm
not typing THAT 18,000 times, so I will only say "Moly." The same goes for MoS2,
the abbreviation for Molybdenum Disulfide, again because of the trouble I would
have to go through each time with the small 2, I will just call it "Moly."
Keep in mind Dow
Corning will be mentioning lubricants, pastes, oils, greases, and bonded
coatings. Moly has been adapted for shooting without the need of other elements.
Space prevents me from
running their entire book and the second half is so technical most of us
wouldn't understand it. Dow Corning sent me a photocopy since the original book
is out of print. I reduced the pictures to fit here. They will give you an
understanding of how "Moly" works. After the pictures, I talk about how this
applies to a barrel and bullets.
The opening page states
in part:
"The problems of
friction and lubrication are mainly surface problems and the scanning electron
microscope is an excellent tool for studying the surfaces of solids. 'Moly,' a
solid and a lubricant, is an ideal subject for study. The features of scanning
electron microscope that make it so ideal studying the mechanism of lubrication
of 'Moly' are:
1. Magnification up to
20,000X.
2. Direct examination
of the surface without pre treatment, which might ruin important information.
3. Depth of focus that
gives three dimensional information in single pictures.
These advantages are
particularly useful in studying the mechanism of 'Moly.' The following sequence
of pictures tells its own story with the help of only a few words of
explanation."

Fig. 14
"These rough surfaces
become very smooth after application of a solid lubricant. A 'Moly'-film starts
to cover the asperities (roughness) of the metallic surface. (Magnification
1300X)"
"THE FOLLOWING SERIES
OF 8 PICTURES SHOWS THE LUBRICATION PROCESS OF MOLYBDENUM DISULFIDE FROM A LOOSE
POWDER TO A STRONGLY ADHERING SMOOTH FILM ON A METAL SURFACE;

Fig. 15
'Moly' powder consists
of conglomerates (clusters) of many small flakes which give the grains the
appearance of a round shape. (My comments: Notice the two in the center standing
on end, they look like a couple of almonds. If you look close they are in
layers, much like a sheet of plywood.)"
"If 'Moly'- powder is
sprinkled on a metal plate, not all of the powder grains are orientated parallel
to the metal surface because they are not flat in shape."
"However, when a steel
ball slides over 'Moly' - powder sprinkled on a steel plate, the single
aggregates are flattened and adhere very strongly to the metal surface."
"A higher magnification
shows that the mechanical stress induced by the ball has produced flat planes
from the round grains."
"At still higher
magnification, it is seen that the lamella (thin plate) layers of 'Moly' single
crystals are pushed apart by the mechanical stress of the steel ball. Easy
sliding of layers and adhesion provide 'Moly' with excellent film forming
properties. (My comments: The 'Moly' shingles out in this process. It's much
like taking a deck of cards on a table and applying pressure with your hand. If
you push the cards to the far side of the table, the cards will shingle, one
overlapping the other. Look closely at the flattened particle in the center
(shaped like an arrow head), and you can see this shingling effect.)"
"The result of the
sliding action of the ball after several passes over the same area is to cause
the 'Moly' platelets to spread out and cover more of the steel surface. When a
smooth 'Moly' - film is formed on the metal surface, no more sliding of 'Moly' -
layers is observed. This thin coating protects the metal surfaces from wear and
provides them with a smooth solid lubricant film."
"A cross - section of
the 'Moly' - coated metal surface is shown next. A thin, solid 'Moly' film (a)
of 2 microns thickness adheres to the surface and prevents metal to metal
contact, thus reducing friction and wear." (My comments: Notice the shingled
"Moly" has formed a bridge from one high point to the next, not filling in the
low spots).
"A single asperity of a
sandblasted metal surface was plastically deformed underneath the 'Moly' - film.
As the surface roughness is reduced, the area of contact beneath the 'Moly' film
is increased. Therefore, the load is distributed over a larger area . . . No
Seizure . . . No abrasive wear."
"THE FOLLOWING THREE
PICTURES DEMONSTRATE THE APPLICATION OF MOLYDENUM DISULFIDE IN METAL FORMING."
"A metal surface after
deep drawing is shown. The lubricant is mineral oil. Many cracks have damaged
the surface as the photomicrograph indicates."
"Application of a
'Moly'- containing lubricant creates a solid lubricant film covering the
surface."
"After deep drawing,
the 'Moly' was removed. There are no cracks and no damage. The small slip bands
demonstrate free metal flow during operation. No metal to metal contact
occurred." (My comments: That no man's land called the throat can be covered and
conditioned so there is no metal to metal contact.)
There is one section in
the rest of the book that shows and explains that the "Moly" film makes a
hardened zone three times harder than the metal itself.
CONCLUSIONS
The excellent
lubricating properties of 'Moly' are due:
- To
the ease of sliding of 'Moly' - lamellae.
- To
the good adhesion of these lamellae to metal surfaces.
- To
the ability of these lamellae to form a homogeneous thin film.
-
This film has a very low coefficient of friction and withstands pressures
exceeding 500,000 psi."
(My comments: In
other parts of the book that I could not get to because of space limits, they
showed that the "Moly film only builds to a certain thickness and does not grow
any thicker. Dave Brown said "Moly either burnishes into the metal or it goes
out the bore, it does not accumulate and it does not foul.")
My Comments: If
you "Moly" coat your barrel and bullets, you will no longer have metal to metal
contact. There will be no high spots to tear copper jackets from the bullets.
The copper fouling is greatly reduced and cleaning the barrel is extremely easy.
Spray Moly
After Dave Brown showed
me the Dow Corning book and the pictures under the electron microscope, he said
a few things that made sense. "When people moly coat their bullets with powder,
then they have to transfer that moly to the bore by firing twenty rounds or so
(after completely cleaning out all of the old copper and carbon fouling)."
Dave continued "As you
fire the first of those twenty rounds, moly is deposited on the bore just ahead
of the throat by an inch or so, then the next round deposits another inch or so
down the barrel. The heat and pressure shingles the moly and forms the bridge
across the high points of the metal." Photo in fig. 21.
He asked, "What happens
in front of the area that has been molyed as the bullet travels down the bore?"
I replied, "You are depositing copper and carbon fouling ahead of each molyed
section." "Right," he said, "and you are molying right over it."
"Spray moly is about
one twentieth the size of powdered moly. It is suspended in a distillate that
evaporates off quickly, if the barrel or bullets are warmed to about 150 degrees
or warm to the touch; by the sun, a hair dryer, a heat gun or in the oven."
Dave said, "The small
particles of the spray moly make them ideal for conditioning the bore. Picture a
gravel road up close. The roughness is much like the picture in fig. 13. When it
starts to snow, the low spots are filled in first and the snow builds up until
the high spots are covered. Now when a car drives over the road, it packs down
the snow. Then several cars drive over the area. Pretty soon, the road is smooth
as glass."
"You don't have to
worry about excess, because the moly will burnish into the metal or go out the
bore."
"The reason you moly
your bullets is to keep the moly from wearing out in the barrel. If you shot
non-molyed bullets down a molyed barrel, you would transfer the moly from the
barrel to the bullets and eventually wear down to the high spots and re-deposit
copper fouling."
My Comments: I talked
to a lot of people and got comments both for and against conditioning the bore.
Jack Krieger, Charlie Milazzo* and Dow Corning all said, "Conditioning the bore
is a better way to go."
*Charlie says "If
you're going to use moly it is the logical way to start. But not everyone is
going to be able to use and stick with moly right now. Eventually it will
probably become the standard. For those who do not have access to moly coated
bullets or approved factory loaded ammo, moly coating of the bore proves to be
nothing more than the introduction of a variable into the accuracy equation.
Consider carefully before firing any moly coated bullets through a barrel which
will primarily be used with standard uncoated projectiles, or before coating the
bore with moly. For some folks that introduced random unknown could eat you
alive. Consistency is the key to dependable accuracy. Changing
bore conditions compromises, at the very least, any consistency."
"There is going to be a
transition period with molyed bullets. Where everything will be in flux. This is
it! There's going to be a lot of wild claims and most likely some problems. We
can only try to recognize the possibilities before they occur to help reduce or
eliminate the stumbling. How do I feel about moly? I think it has tremendous
potential."
Moly Snobs
During my talks to all
these different people, I coined a phrase, "Moly Snob." People who are already
using powdered moly did not even want to hear of spray moly. They didn't want to
put anything in their bore (Sorry Bubba, you ARE putting moly in your bore when
you shoot the powdered bullets). "I don't want to condition my bore." Again, you
ARE conditioning your bore with the powdered molyed bullets, you are just doing
it inefficiently.
Moly Snobs remind me of
the people who say: "My Chevy truck is better than your Ford truck and I'll put
on the decal of the little boy peeing on your logo to prove it."
People have their own
cleaning techniques and ideas of molying to the point of dogma and/or religion.
They will (verbally) fight to the death to prove "My Moly is better than your
moly."
Back to Dave Brown's
demonstration. He then showed me how to use his product "Ms. Moly" on a barrel.
You need to warm the object, barrel or bullets, first. Warming them evaporates
the distillants quickly and the moly dries instantly.
He has as part of the
kit a couple pieces of polyethylene with a series of holes punched in rows. He
calls them the "wholly organizer." You simply set the organizer on a flat
surface like a pane of glass and drop the warmed bullets into the holes. When
the organizer is full, lift it up and off.
What remains is row on
row of bullets standing at attention like a platoon of soldiers ready for
inspection. You then shake the can of "Ms. Moly" and spray; front, back, right
and left. You may want to give a second coat from the four corners.
I immediately picked up
one of the bullets and it was dry; no moly came off on my hand. Powdered moly is
messy, but washes up with soap and water. Dave said, "Try to scrape it off with
your finger nail." I tried and could not.
A friend was at a match
and a Sgt. on the Marine Corps Team asked to look at his molyed bullets. He
scraped some off with his fingernail and told Andy, "You have to tumble them
longer. The moly should not scrape off."
How do you Moly the bore?
Dave Brown suggests you
first try it on a shotgun barrel because it is so much bigger and you can see
what's going on. He recommends you place a patch or cotton ball in one end. If
you are dumb enough to do this over your wife's carpet, you are a candidate for
natural selection.
Again, heat the barrel
until it is warm to the touch. Hold the barrel so the bead is up or at the 12
o'clock position. Shake the can of moly and give a two second spray down the
barrel. Turn the sight down to the 6 o'clock position and give another two
second spray. Do this again at the 3 & 9 o'clock positions.
Remove the patch or
cotton ball and place it in the end you just sprayed. Repeat the procedure from
the other end, 12-6-3 and 9 o'clock positions. Now look down the bore and you
will see the moly start to weep or run. Now brush the bore to burnish the moly
into the barrel. This is the first application; you need to give it three
applications.
I looked down the bore
of the shotgun barrel and it was very bright. Dave Brown said, "Turn it around
and look down the other end." When I did my head snapped back. The bore was sooo
bright, it was like being hit with a spotlight in a dark room.
I also noticed some
little black beads in the bore (the barrel had been previously fired). It seems
the carbon fouling beads up much like rain drops on a polished and waxed car.
They are hard, black beads and you would have to be blind not to see them. After
a rifle match, I took the lower receiver off to reduce the weight. I placed a
clean, white patch near the chamber and held it up to the shop light. The
reflected light down the bore showed the black beads of carbon fouling. After
cleaning, I could see the two beads I had missed.
Defending the Lady's Honor
I was told by one of
our regular shooters "Ms. Moly spray has graphite in it and should not be used."
As proof he FAXed me a Material Safety Data Sheet from Dow Corning for Dow
Corning 321 Dry Film Lubricant (Aerosol)® . Yes, it has 3% graphite.
I called David Brown
and asked if he re-labeled Dow Corning 321 Dry Film Lubricant (Aerosol) as his
own "Ms. Moly." He told me no, that his spray is made for shooting, with no
graphite. He then FAXed me his Material Safety Data Sheet on "Ms. Moly"
showing there is no graphite.
The next assault on the
Lady's honor came when several people decided there had to be some "Binders" in
the spray to make the moly stick to the bullets. Again, the Material Safety Data
Sheet rode to the rescue; no binders.
This did alert us to
the fact that some spray molys have graphite in them. You don't want graphite in
your bore, because it's an abrasive.
I part company with one
thing Dave Brown said, "It's OK to moly the chamber." A lot of people say NO and
some say yes. Boots said it probably would be all right, but Charlie says,
"Boots knows what he is doing when it comes to loading. There are a lot of
people who may not recognize the fact that they could get into some serious
trouble. Reduced friction between the brass and chamber wall equals increased
thrust on the bolt face and locking lugs."
If you are going to
spray the moly into the breech end, use the rod guide with the "O" ring to keep
the moly away from the chamber. You can spray a patch or mop, then apply it to
the bore and burnish it in with the bronze brush.
Another Method
NECO MOLY-SLIDE® is a
paste and comes in a one ounce plastic tube. It contains no graphite. It
contains approximately 60% laboratory-grade, extremely small, micron-sized Moly
in paste form. It takes a VERY small amount to go a long way. Some people are
using the NECO MOLY-SLIDE® to condision the bore and to touch up after cleaning
to elimiate the need for fouling shots after over-cleaning. You can order the
NECO MOLY-SLIDE® direct from NECO, 800-451-3550 or from O.K. Weber.
Removing Moly
Someone told me you can
not remove the moly once it is placed in the bore. When I told Dave Brown that,
he showed me a new product he will soon have available. He sprayed it on a
molyed bullet and it instantly removed all the moly. I have since learned MEK,
methyl ethyl ketone, will do the same thing and you can get it at the hardware
store.
My Conclusions on Spray Moly
Spray moly will not
replace powdered moly! It simply cannot compete economically. I have been told
the 4 oz. of industrial (1 micron) powdered moly will do 20,000 to 40,000
rounds. The 10 oz. bottle of regular (5 micron) moly will do 50,000 to 100,000
rounds for under $35.00.
For conditioning the
bore, the spray moly or NECO Molyslide® paste is "The better way to go." It is
faster and cleaner than powdered moly. If a person lives in an area without a
workshop, basement, etc., like an apartment, the spray is ideal.
When we go shopping for
our food, if we want something fast and easy to prepare, we are willing to pay
more. If we want economy, we buy things that will take time and effort to
prepare. It's all a trade off.
Spray and powder each
have their place and can co-exist. I believe the spray is best for conditioning
the bore and quick and easy for molying bullets when you are in a hurry or small
quantities of bullets or fixed ammo which do not merit all the trouble of
tumbling. Powder is best for the long haul economics.
Powdered -Moly
"Guns and Ammo"
magazine ran an article called 21st - Century Accuracy by Tom Gresham. It
said, in part:
Bullet break -
throughs
A bullet - coating
process developed by (NECO) Nostalgia Enterprises Company (510/450-0420)
involves tumbling bullets to "impact plate" them with Molybdenum Disulfide, then
following up with a coat of carnauba wax. The result: greater accuracy, reduced
friction, reduced bore - fouling and, in some cases, reduced bullet - drop - -
with the same velocity. Walt Berger, president of Berger Bullets (602/842-4001),
said his bench rest rifle now has more than 800 Moly-coated rounds through it
without having seen a brush - - he cleans with only a wet patch and a dry patch.
NECO offers kits for do-it-yourselfers; Berger will Moly-coat any of his bullets
for an additional charge of only $2 to $4 per 100 bullets. "Within two years,"
he says, "every ammunition company will have to offer Moly-coated bullets."
This article was taken
off the Internet and was mailed to me by the gentleman at Dow Corning. The phone
numbers in the article opened new doors in my quest for information. I called
NECO and talked to Roger Johnson, the man in charge. After introducing myself
and telling him about this book, I had some questions and some "feed-back" for
him.
I asked "How much does
your kit cost?" He replied: "$137.35." (I have seen them advertised for $148.00
from other distributors). I then asked "What does the kit include?" He said "1)
4 oz. jar of one micron Moly powder, 2) 13 1/2 lbs. of 5/32 Dia. ground steel
balls, heat treated to Rockwell C50, 3) 3 oz. of carnauba wax, 4) a sample
bullet and 5) a complete instruction manual."
I told him, I had some
feed-back from shooters who are using powdered Moly, some with his kits and they
are not using the wax. In fact, some are warning against using the wax because
it is causing problems. He said, "We have not heard of any problems and the
people who are giving up on the wax don't know what they are losing. Norma says
that they get 10 - 35% better ballistics depending on the barrel."
He has a product called
Moly-Slide (I picked up a tube from O.K. Weber at Camp Perry in 1997). Roger
said that he will condition a new bore with the Moly Slide by putting some on a
patch and running it down the bore. It is also good if you get over aggressive
in your cleaning and take the Moly out of the bore. A touch up will re-Moly the
bore and you don't need the extra bullets to do the job.
Roger told me something
else that I found interesting. With products that have ammonia in them like
Sweets, he neutralizes them with water. He then dry patches the bore and
protects it with oil. The oil must be cleaned out before you shoot the next
time.
One thing Roger told me
of which I was not aware. Moly DOES NOT protect the bore from moisture
and humidity. He uses a light coat of oil while storing the rifle, again
cleaning out the bore before shooting the next time.
Midways' Kit
Midwayâ (800)-243-3220
has a Deluxe Pack (8 oz. Moly & 2 #1292 hard plastic bowls) #610-434 for $34.99.
They also have their Ultimate Pack, a #1292 Tumbler with an extra bowl and 8 oz.
of Moly, #480-460 for $69.99.
When I called to ask
them about their kit, they told me they don't use the steel balls, as the
bullets themselves do the impacting. OK, I need to know, "Does this work?" I
called a Friend because I knew he just bought a tumbler, Moly and some steel
balls and was going to run his first batch that evening. He said he would try
them without the steel balls. The next day he called and told me he ran 1,000 of
the 69 gr. bullets and they came out perfect. The following day he called back
saying he ran 1,600 of the 69 gr. bullets and again they came out perfect.
OK, How did he do it?
He simply put the bullets in the tumbler and added 4 oz. of Moly and ran them
for two hours. After shutting the tumbler off he used a slotted serving spoon to
pick up the bullets and sift out the Moly. He then placed them in an old sock to
rub off the excess Moly (a towel or paper towel works fine). Then he put the
bullets in a ZipLoc® bag or back in their original boxes. You can add a little
Moly to each new batch or run the Moly that's in the tumbler until its gone. (OOOPS,
I just talked to Midway and asked them how they did it. I liked their answer
better; they use 1/8 teaspoon of Moly for each five pounds of bullets). Fast,
Simple, Easy, and Inexpensive. Powdered Moly is messy, but it cleans up with
soap and water.
Sources of Moly
Here is a list of
places I know of to get Moly that will do the job. 1) NECO, (510) 450- 0420 has
a 4 oz. container of ultra fine (1 micron) Moly #MC-12 for $42.75. 2) Dow
Corning has a 10 oz. bottle of 5 micron Moly called "Z-Powder." They do not sell
directly to the public but if you call them at (517) 496-6000 they will give you
the name of a company in your area that caries the Z-Powder. In Milwaukee it was
Wisconsin Bearing and they sold the 10 oz. bottle for $32.86. 3) Midway (800)
243-3220 buys the Z-Powder in large quantities and sells an 8 oz. jar #677-866
for $19.99. Now you need a rotary tumbler or a vibrator tumbler; either will
work fine.
Joe Blow Schmuckatelly
Joe asked me not to
mention his real name (in fact, Joe is a composite of 4 or 5 different people).
Joe said that he found with the NECO kit's instructions they have a ratio of
bullet weight to steel ball weight. He simply used a 12 oz. coffee mug to weigh
the bullets. A few 180 grs., or a lot of 69 gr. bullets come out to the proper
ratio. He says the coffee mug works great. So, fill your coffee mug with bullets
and level off the top. Pour the bullets into the steel balls , add a squirt of
Moly (about 1/8th teaspoon) and let it run for a couple of hours. Joe says he
uses a plastic pail with holes drilled in the bottom to separate the bullets
from the steel balls; a Dillon media separator works also. Now put the bullets
on a terry cloth towel (paper towels work) and rub off the excess Moly. You
should not be able to scratch off the Moly with your finger nail.
Andy Ladron called and
said, "It doesn't work. I ran them for two hours, added more Moly then ran them
another two hours, then added more Moly again and again." He has a tumbler with
a rubber liner. The Moly was soaking into the rubber. You need a tumbler
made of hard plastic.
Do you have to clean the bullets before
molying?
If you are using
Hornady bullets (not seconds), just dump them right in the bowl. DO NOT touch
them first, the oils on your hands will prevent the Moly adhering to the
bullets. Some people have acidic sweat and the Moly will not stick. If you have
to handle the bullets first, use cotton gloves. Some of the other bullet makers
have a film on the bullets that must be removed before you can Moly them.
Running the bullets in a corn cob media will clean them or you could try MEK or
acetone. (Again, OOOPS, I just talked to Midway and they said you can run the
bullets in Dawn dish washing soap and water to remove the grease, then air dry
them).
How do I clean the bore and break in the
barrel?
Two very important
questions, with the usual thousand answers. The one I like best came from Berger
Bullets (Questions & Answers) @ http://www. bergerbullets.com/faq.htm Reprint
follows:
1. How do I clean
my rifle using Moly Coated bullets?
The best procedure for
cleaning when using Moly coated bullets is as follows:
-
Two wet patches with Kroil.
-
One patch with JB bore cleaner. Short stroke the patch from the breach to the
muzzle.
-
Two wet patches with Kroil.
-
Two dry patches.
This procedure is
suggested after approximately 80 to 100 rounds, depending on the class of rifle
being fired.
2. How do I break
in a barrel with Moly Coated bullets?
The procedure that Walt
has found to be the best is as follows:
-
Run a wet patch of Kroil through the barrel.
-
Fire one shot then clean using our cleaning procedure.
-
Repeat step 2 two more times.
-
Fire 3 shot groups 5 times cleaning after every 3 shots.
Your barrel will now be
broken in.
What is Kroil and where do you get it?
When I asked that
question, I was told, "It's a penetrating oil you can get anywhere." "OK, the
next time you're at McDonalds, pick up a can," I said. "You can get it at any
auto parts or hardware store." Oh yeah, three auto parts stores and two hardware
stores later, I got tired of hearing "We never heard of it." Sinclair (219)
493-1858 has it in their catalog. The first time I heard of Kroil was when Mid
Tomkins told me he uses 50% Kroil and 50% Shooters Choice as his bore cleaner
(other shooters have said they use 2 parts Hoppes to 1 part Kroil).
Another Cleaning Method
Another cleaning method
came from Grant Ubl. He runs a couple of wet patches soaked in Shooters Choice
down the bore. Then with a plastic or nylon brush wet with Shooters Choice, he
scrubs the bore. He will then dry patch the bore. Here is the interesting part,
he says you will never stop getting black from the Moly, but he will run an
EXTREMELY tight patch down the bore until he gets minimal amounts of black on
the patch.
The above method is
used when he has to shoot the next day (remember, over aggressive cleaning
removes the moly). When he has unlimited sighters, (to remoly the bore) and
wants to get a little more aggressive, he uses the following method: He runs
several wet patches with regular Shooters Choice, followed by Shooters Choice
Copper Remover. Dry patch, then he uses JB Bore Cleaner to scrub the bore,
followed by wet patches of Shooters Choice to flush the JB, then dry patches. He
says he'll need 6-8 rounds to re-moly and all is right with the world.
A Word of Caution
Dave Emary from Hornady
called and told me some of the 50 cal. shooters are reporting that some of the
moly has sulfur in it and the bore cleaners with ammonia is forming a chemical
reaction that is etching the bore. I was offered some moly and I checked the
Material Safety Data Sheet; it had 40% sulfur. I said, "No Thanks."
A passing fad?
One of the Moly Snobs
said "This Moly Coating is a passing fad and everyone is jumping on the band
wagon." He doesn't like to try anything new until it's been around for fifty
years or so.
I have personally seen
increased accuracy and easier cleaning with Moly coated bullets. I know someone
who keeps excellent records, showing less throat erosion (longer barrel life). I
talked to long range shooters and Police Officers (SWAT) who say the first shot
is right there. I have talked to experts in the field who say one can shoot more
rounds between cleanings before accuracy drops off.
If only one of these is
true, move over; I'm coming aboard this band wagon!!!
Update
Moly Coating Bullets - Quality Results;
Simply and Economically
By
Jon Wilcox
I now have three years
production experience moly coating bullets. How I do it is a massively lower
cost alternative to commercial kits in the marketplace. I started in 1997,
wanting to coat bullets, but unwilling to buy more tumblers and other equipment.
Since I already had a huge Dillon tumbler, I considered ways to use it instead.
I purchased 10 oz. Corning Moly Powder from WI Bearing for about $28. Midway now
sells 8 ounces for $20. Either amount may turn out to be a lifetime supply for
you.
I tried a number of
processes, settling on small containers which would fit inside the Dillon
tumbler bowl. As it turned out, the best ones were 18 ounce plastic peanut
butter jars. Skippy, Jif and the store brands have this size. The jars are clear
plastic and small. The smallest size,12 ounce jars, will also work for smaller
batches, but the 18 ounce size seems to work the best and allows the greatest
throughput.
The beauty of this
system is that tooling for this moly kit costs merely the cost of the peanut
butter jar. This assumes that one already has all the other equipment from one’s
reloading interests, and that one eats peanut butter. If one wishes to use steel
shot as in the NECO kit, fine. Inexpensive Copper BB's will work, but I find
this is not needed. My moly coat will not scratch off, and my bullets look every
bit as nice as any I have ever seen with any process.
One may be satisfied
just coating bullets with moly; many are. There is some difference of opinion
about waxing bullets and the benefit or detriment of same. For two years I did
not wax. My bullets smudged little and kept their coating just fine. They shot
just fine as well. The benefits of easy cleaning and the lengthened period
between cleaning were completely realized. Barrel wear seems markedly reduced as
compared with bare bullets. Accuracy does not seem to vary much from bare
bullets, but groups seem to be more uniformly shaped, using moly.
In 1999, I decided to
add wax coating. By then, I was learning of suspected intangible benefits from
the wax. Boots Obermeyer, and Norma were speaking of having observed better
results with wax. Boots spoke in terms of lowered standard deviations. Norma
declares there is a benefit, but can not solidly quantify their belief. They
just know.... Merrill Martin has posited that prevention of barrel erosion may
be from an ablative effect which the wax provides.
Until 1999, an obstacle
to waxing was the difficulty in obtaining powdered carnauba wax separate from
the expensive kits. After some searching, I was able to find it. You can now
obtain Kincaid’s Custom powdered carnauba wax in three once bottles from
Sinclair International for $8.00. This amount may also turn out to be a lifetime
supply for you.
If you wish to try
waxing your molyed bullets, my easy process is quick and inexpensive, again
using peanut butter jars and the tumbler you already own. When both molyed and
waxed, my bullets look as fine as Janell’s hematite jewelry. In fact, grey
hematite jewelry is my quality standard of comparison for properly molyed-waxed
bullets. I am currently very satisfied with the beauty and cleanliness of my
bullets when both molyed and waxed. My uniform results come from the following
process which evolved from continuous experimentation and improvement over the
past three years.
General
Considerations:
No shot is used with
this moly-coat process. The bullets themselves are able to burnish the moly onto
each other, as long as the container is small enough to keep them close
together. I have successfully molyed and waxed batches of bullets as small as
1000 grains. Batches for moly coating and waxing should not exceed 12,000 grains
(nearly 2 pounds) per container. Exceeding this weight prevents the jars from
rotating adequately in the tumbler. The moly will not be uniformly applied and
points of bullets will suffer damage. Two hundred .22 caliber bullets up to 60
grains can be done in one batch. Bullets larger than 120 grains must be done in
split-box batches to insure a good result. This is not a hardship. One can place
five, 18 ounce peanut butter jars in a large Dillon tumbler at one time.
Step ONE - Clean and
Dry the Bullets
Clean oil and tarnish
from bullets in a plastic container (I use a 28 ounce clear plastic peanut
butter jar) with just enough 5% household ammonia & water solution to cover
them. This will be 1cup or so of solution - 1:1 ammonia and water; ½ cup of
each. Swirl occasionally. Total time swirling and soaking is five to ten
minutes, maximum. The solution will turn blue, as the reaction and cleaning
proceeds. Possibly some light etching may be happening as they clean.
Thoroughly rinse the
bullets (3 times or more) under hot water. Dry on a soft cloth or premium grade
sturdy paper toweling. Transfer the bullets to a dry surface, allowing
additional time for the heat in the bullets to completely air dry them before
the next step; approximately 20 minutes. Save the paper toweling for step three.
The paper toweling will have dried by then. Avoid touching the bullets with your
fingers.
Step TWO - Tumble
with Moly Powder
Place no more than
12,000 grains of bullets in an 18 oz. peanut butter jar (no BBs, just bullets).
Place 1/8 teaspoon of moly powder onto the inside of the jar lid cardboard (to
be sure of the amount), then dump it in the jar. Tighten the lid firmly to avoid
leakage. The cardboard seal should be kept in the jar lid. Use twice as much
moly when using a new jar, as the plastic seems to suck up some of the moly.
Lay the jar in the
tumbler on the media in your tumbler. You may, if you like, clean cases in your
tumbler while you do this. It does not adversely affect the process - it might
even help the jars "roll." Without brass being tumbled, the process is quieter.
Observe the jar "rolling" slowly in the media in the tumbler to determine which
way the jar rolls. Situate the jar so the rolling action serves to tighten the
lid, not loosen it. Place the lid on your tumbler (dust consideration) and let
the tumbler run for about an hour. I have experienced good results in only one
half hour, but I am always satisfied with the moly coating after an hour.
Tumbling bullets in moly for longer than an hour will not hurt. Three and four
hours tumbling unattended has worked fine.
Step THREE - Polish
Molyed Bullets
Remove the jar from
your tumbler. Loosen the jar lid while tumbler is still running, using the
vibration to help knock loose corn cob grit from the outside of the jar and the
jar lid threads. Pour your bullets out on an old T-shirt, rag or sturdy premium
grade paper towel set in a shallow cake pan. Polish the excess moly off of your
bullets by gently shaking them back and forth on the toweling in the pan. This
works well in 15 seconds or so. When you have finished, you will have beautiful,
low-shine moly coated bullets which will smudge little. Check the coating by
trying (with some effort) to scratch the coating off with your fingernail. You
have done well if the coating will not scratch off. Do not be concerned about
cannelures being uncoated. There is no impact possible in the cannelure, so moly
can’t "plate" there.
Step FOUR - Carnauba
Wax Your Bullets
Place the polished
molyed bullets in the sun under a clear cover for 20 minutes to heat to 115EF.
Alternatively, place them in your oven at low heat for 10 minutes to warm them.
Be careful with polycarbonate tipped bullets, such as the Nosler Ballistic Tips,
Hornady V-Max, or Sierra Blitz-Kings. Their tips will pop off the bullet (it
sounds like popcorn popping) if the heat goes too high.
Half fill an 18 ounce
peanut butter jar with clean corn cob media. Place 1/8 teaspoon of the powdered
carnauba wax onto the inside of the jar lid cardboard (to be sure of the
amount), then dump it in the jar. Do not use too much wax, as it will clump and
your bullets’ coating will come out looking mottled and sickly. Use twice as
much wax the first time you use new media, as the media will absorb wax. The
media is a moderator in this process, assuring that neither too much nor too
little wax is deposited on the bullets. The media is reusable until it becomes
too dark with moly.
Add the warm bullets to
the jar, again observing the 12,000 grain limitation per jar. Immediately lay
the jar in the tumbler on the media in your tumbler. You may clean cases in your
tumbler while you do this. It does not adversely affect the process - it might
even help the jars "roll." Without brass being tumbled, the process is quieter.
Observe the jar "rolling" slowly in the media in the tumbler to determine which
way the jar rolls. Situate the jar so the rolling action serves to tighten the
lid, not loosen it. Set a timer for ten minutes. Allowing this process to
continue longer than ten minutes will begin to degrade the wax coating. At ten
minutes, immediately remove your bullets and sift them from the media. I use a
cat box kitty litter scoop to do the separating, shaking out about ten bullets
in a scoop.
Your finished bullets
will be silvery-grey, hard wax coated with a high shine. Their appearance will
rival grey hematite jewelry and they will feel as slippery as a fresh waxed
automobile panel. Place the bullets in their boxes. They are ready for loading.
