Sight Alignment, Trigger Control and The Big
Lie
CHAPTER THREE
I always thought that
when I got to be elderly that being a "dirty old man" was going to be fun. No
one told me that you lose your eye sight and your hearing, your body aches all
over, and you get ugly. Oh well, I saw a sign that says, "Old age ain't for
wimps."
APERTURE SIGHTS
I learned to shoot
aperture sights long before my eyes started to go and I'm glad I did. I will
admit that it helps tremendously to be young and have good eyes to shoot a
"post" front sight. Aperture sights, sometimes called "globe" front sights, are
far easier on the eyes. There is no need for the constant focus.
With the aperture,
sight alignment and sight picture are the same. You have three concentric
circles. The rear sight, the front sight and the aiming black must all
have the same center.
When you look through
the rear sight, make sure you have the same "eye relief" each and every time.
Once again, eye relief is the distance from the rear sight to your eye. It is
controlled by the placement of your cheek on the same spot of the stock, known
as "stock weld," or the placement of your cheek onto your hand (usually the
thumb), known as "spot weld." Make sure you are looking through the center of
the rear sight.
The front sight is an
aperture, or circle, and it must have the same center aligned with the rear
sight. Place the aiming black into the front aperture and its center must be
concentric with the others. Having an equal amount of white around the aiming
black ensures that it is centered.
Everything I have told
you to this point is true - as far as it goes. That was all that I was taught,
and I made the same mistakes most new shooters make. Through a lot of trial and
error, I started to learn what works and what doesn't.
THE MOST COMMON MISTAKES
MADE BY NEW SHOOTERS
For the most part, High
Power Shooters are great people and are willing to help. Remember, on the firing
line, the seasoned shooter is trying to get ready for the same match you are. He
may be getting mentally prepared and if you ask a lot of questions, it may be
irritating. After the match, you cannot go up and say, "Tell me everything you
know." That could take awhile. You have to know what questions to ask.
After much "trial and
error," I found the correct method and amount of adjustment for both the front
and rear sights. One day, I knew the right questions and who to ask. Col. Sam
Burkhalter has been the Senior National Champion more times than he cares to
admit, and when it comes to helping other shooters, he is a gymnast of the first
order. He will bend over backwards to help.
During one
conversation, Sam said, "That's right! Most new shooters have the front aperture
closed down too far, and the rear aperture opened up too far."
THE REAR SIGHT
During your prep time,
closed down the rear sight aperture all the way, slowly open it to
the point where a flood of light comes in and your eye relaxes. STOP at
that point. DO NOT open it any further. This is not a case of "if a little is
good, a lot is better." Opening it further will be much like the improper focus
with the post front sight. You will get wide shots - nines when they should be
tens or Xs.
Let's talk about the
Match Rifle rear sight. Today's technology makes the sight almost a work of art
and you can get one with all the "bells and whistles" like I did. I have both
the Warner and Zelenak sights and they both are excellent sights - both come in
1/4 or 1/8 minute clicks and both require the aperture to be purchased
separately.
The Gehmann aperture is
a fine choice. Here is where all the "bells and whistles" come in ... but also
the trouble! The features available are: adjustable iris, polarizing filters,
five colored filters and a diopter. The adjustable iris is a must; it is
the part that opens and closes to let in more or less light. This is the one
most new shooters open too far. The ability to open or close the rear aperture
is one of the match sight's strong points and you do want it.
The sight comes with
two polarizing filters which are nothing more than a lens with finely etched
lines very close together. As you drop the filter down into the line of sight,
it refines or filters to one plane of light, and gives the aiming black a sharp,
clear contrast against the background. It's mostly used on a bright day and it
will cut the glare. I only use one of the two filters because using both just
makes it too dark. When I first got the sight, I thought there would be
instructions on how to use the polarizing filters. There were instructions, but
they were in German and with a lot of effort I had them translated - it was how
to break the filters down for cleaning, not how to use them. Using only one
polarizing filter works fine for me. It is a nice feature and you will like it.
SAVE YOUR MONEY
Unless you are among
the one or two percent of shooters who use a lot of colored glasses in different
light conditions, save your money and don't get the aperture with the five
colored filters. You'll find you just don't use them.
I didn't know what a
diopter was until I saw one at Camp Perry. A diopter is a magnifier, either on
the front or the rear sight. You may not use both. It is said to act as a
telescope and is not legal. (More on the front diopter later).
When I first got the
Gehmann aperture with the rear diopter, the salesman said: "Hold it up and look
through it at a distant object and turn the ring." It was like a miniature
spotting scope. You could bring the distant object into focus, just like a
scope. You could see the aiming black clearer, sharper and bigger (closer). You
can use it at all ranges from 200 yards to 1,000 yards. "Oh boy, I've got to
have this."
I bought the rear
diopter at Camp Perry
in August and used it up until the beginning of October, with no problems. When
we started shooting in April, I was having one hell of a time shooting. My shots
would go wide at
nine o'clock and I would come right. It would be all right for awhile, but then
I would get another wild shot out the left and again come right. It kept doing
that for sometime. "Someone said, "It's early in the season. Everyone has
problems. You'll settle in." For three matches, my scores went from High Master
down to Expert. I was ready to sell a $500 sight for $75. Luckily, Rocky, one of
the shooters on the line, didn't take me up on the offer.
I gave the sight to
Boots Obermeyer to check out. He put it on a dial indicator and found it was
tracking perfectly. "It might be the diopter," he said. I told him, "I know how
to find out." On the next Wednesday night practice, I put up a 600 yard reduced
target at 200 yards and from the prone position, I fired my first ten shots -
the same problem continued. I got out of position and removed the aperture with
the diopter and replaced it with a plain aperture with just an adjustable iris,
no diopter. I laid back down and fired the second shots and got a 99 with
6 Xs. I talked to the salesman at Camp Perry that year, and he said, "The rear
diopter was made for Small Bore shooting and High Power shooters discovered
them, but they are not designed for the punishment and shock High Power gives
them."
Save your money
- stay away from the rear diopter. (Since this was first written, Bob
Jones has come up with some rear diopters especially made for High Power) By
dropping from High Master to Expert, I knew something was wrong. A Marksman or a
Sharpshooter may think, "It must be me" and he will continue to shoot with bad
equipment. Your RIFLE, SIGHTS, AMMO and EQUIPMENT must be better than you
are. If any one of these is a limiting factor, you will shoot up to "its"
ability and not "yours."
THE FRONT APERTURE
(Logic Takes a Holiday)
When I started to shoot
a Match Rifle with aperture sights I was told about the three concentric circles
and told to line them up with the same center and to make sure the aiming black
was centered in the front aperture with an equal amount of white all around it.
That was all I was told.
Like 98% of the other
new shooters, I made the same mistake. My front aperture looked like Figure 11.
I had too tight a line of white around the aiming black. Logic said that it
would be easier to judge if it was centered and I could pick up small
misalignment of the sights.

Too tight a line of
white actually makes it harder for your eyes to distinguish when you are
lined up. It causes eye strain, fatigue and creates undue tension as you shoot.
It can create a fuzziness and distort the image as you try to break the shot.
By experimenting, I
gradually opened the front aperture and, gradually, I shot better. I read
several articles which said the front aperture should be two or two and a
half times the size of the aiming black (See Figure 12). I was amazed
because my previous logic told me otherwise, but since I was improving by
opening the aperture a little, I tried the suggested larger opening. My scores
got even better.

It may seem a little
strange, but stick with it and the results will show in the improved scores.
Don't try to make your sight picture too good. The aiming black self centers as
you fire your rapid fire. I tried to make it, "Just Right," and it messed up my
timing. In one of the "STAR WARS" movies, Luke Skywalker was learning to use the
light saber - he was told something like, "Don't use your eyes, just 'feel' it,
let it happen." Don't try to make it too good, just feel it and let it happen.
You will be surprised at how much better you shoot and you can call your shots
far better.
During the slow fire,
you want to make each shot just right. Your eyes will automatically center the
aiming black but you are not sure, "Is it centered?" You take it off-center a
little and say "yep, that was centered," and you then re-center it. After
awhile, you will know exactly when it is centered. Quite often, just as it is
centered up, the image will "brighten" just a little. For me, it is like a
one-watt light bulb was turned on and I know it's time to break the shot.
Do not "lay" on the
rifle and take an extra long time. Once you close the bolt, check the wind, make
an adjustment if needed. Place the rifle in your shoulder, roll into it, take
your breath as you are checking your number board, pick up your sight alignment
and squeeze off the shot. You should complete the process in about one half the
time it takes to read this paragraph. If you stare at the sight picture, the
sights will be "burned" into your mind and you can misalign the sights, still
thinking they are correct. 3-5 seconds --- no more.
THE FRONT SIGHTS
I used the "Drop In"
apertures, both metal and plastic. They are all right, but use an adjustable one
once and you'll never go back to the drop in type. I tend to use one setting for
all yard lines on a given day. I use the same setting for off-hand, 200 yard
rapid, 300 yard rapid and 600 yard prone as long as I keep the 2 - 1/2 ratio of
white around the aiming black. The light conditions for this weekend may not
allow the use of the same settings you used last weekend. You may not even think
about it until you look down range through the sights at the start of your three
minute prep time. After using the full three minutes to get the right drop in
aperture, I decided to switch to an adjustable one. You reach up and dial it
like a radio and it takes just seconds.
I'm using a Gehmann
adjustable aperture on an Anschutz base, with a Tiger Eye Diopter.
THE FRONT DIOPTER
If you have ever fired
the 1,000 yard iron sight matches at Camp Perry you know they import the fog
and/or haze just for that match. Finding your own number board twenty times in a
row is a major accomplishment.
I have this little
demonstration I do when explaining a front diopter. I do it at the 200 yard
line, but it will work at any yard line. I first take the diopter out (it just
unscrews) and I have the person look through the sights at the aiming black just
the way it would normally appear. I then screw the diopter back in and I have
them look again. You should see their faces light up. One shooter said, "I've
got to get one of these."
The .3 diopter can be
used at the 200 yard, 300 yard and 600 yard lines. I leave it in for shooting
across the course. Make sure you take it out and clean it before each day of
shooting. It makes the image so much sharper, clearer and larger. You must see
it to believe it. The .3 diopter can also be used for the 800 yard, 900 yard and
1,000 yard lines. You can see your number board and aiming black.
The .5 diopter is best
used at 900 yards and 1,000 yards. It is very strong. Shooting 1,000
yards with a .5 diopter makes it appear as if the aiming black is at only 600
yards. You can shoot so much better when you can see.
I tried the .5 diopter
at 600 yards to see what would happen. I fired the first ten shots with it and
it really brought the aiming black in close. I was getting some pretty
wide shots, so, after the first ten shots, I took the .5 diopter out and put in
the .3 diopter. I immediately knew what the problem was. The .5 magnified it so
much, it looked like Figure 11 and there was too tight of a line of white around
the aiming black. The .3 made it look like Figure 12, with the correct amount of
white, 2 - 2 1/2 times. The second ten shots were all tens and Xs - no more wide
shots.
The adjustable, front
diopter magnifies everything. If you are using the Gehmann adjustable you have
to open it even farther than normal. I was using the model that opened to 4.2
and I had it opened all the way. This didn't leave any room for bad light
conditions. Last year at Camp Perry, I sold it and I got the newer model that
opens to 4.8. Everyone I know that has used the front diopter has liked it. My
recommendation for High Power: "Stay away from the rear diopter. It may never
give you trouble, but if it does it will be BIG trouble."
