Sight Alignment, Trigger Control and The Big
Lie
CHAPTER TWO
In the mid sixties, the
Cherry Point Rifle and Pistol Team shot seven days a week for nine months of the
year. Weekdays were practice, and the weekends were at matches. To liven things
up at one of the practice sessions, Dirty Dave Yingling ( a name he worked hard
acquiring) decided to play a little trick on one of his team mates.
He pasted a repair
center on backwards over the aiming black of the target. He pasted an aiming
black onto the metal scoring disk (a round metal disk painted red on one side
and white on the other, attached to a pole about six feet long) and wrapped the
pole with the white portion of the repair center.
When the targets went
up for rapid fire, he held up the pole with the mobile aiming black in
the center of the target. From the line, it looked like all of the other
targets. He let the shooter pick up his sight alignment and sight picture and
squeeze off the first two shots. After the magazine change and the third shot,
he S-L-O-W-L-Y moved the pole around the target. Now you know why they call him
Dirty Dave.
AIM
Aiming is simply
aligning the front and rear sights in the proper manner. I will cover the "post"
front sights first. I once had a shooter ask a question on the subject and I
told him: "That was covered in the class. Weren't you paying attention?" He
said: "You were talking about the M1A and I shoot an AR-15." "No - I was talking
about the POST FRONT SIGHT, the method is the same for each."
Aiming involves three
elements:
- Sight Alignment
- Sight Picture
- Focus
SIGHT ALIGNMENT
The rear sight is an
aperture or a small hole through a piece of metal -- or a hooded rear sight.
When you get into position, make sure the eye relief (distance from the rear
sight and your eye) is the same each and every time. Do this by placing your
cheek on the stock or on your hand at the same point each time. This is called a
"spot" weld or "stock" weld.
When you look through
the rear aperture, your mind must form an imaginary pair of cross hairs, one
vertical and one horizontal. The front sight post is then aligned with these
cross hairs. The top of the front sight post is brought up even with the
horizontal line and centered. There is an equal amount of the front sight post
on each side of the vertical line (See Figure 4).

You cannot assume the
shooter automatically knows this. We once had a shooter hitting way over the
target. He was putting the BOTTOM of the front sight post even with the
horizontal line.

Figure 5 is an
exaggeration of sight misalignment. The shot will be out of the black. It will
be low and to the right, and most likely off the target at longer distances. A
small misalignment can cause you problems, but don't "get wrapped around the
axle" with the thousandths of an inch - just do it correctly. It must be done
the same each and every time.
SIGHT PICTURE
Sight alignment does
not require an aiming point. It can be done on a blank wall. When you are trying
to shoot at and hit an aiming point you must add the next step - "sight
picture." In High Power shooting, the aiming point is a round circle, a
different size for each distance. The size of the aiming black will appear the
same at all distances.
The most common sight
picture used is the "six o'clock hold." The sight alignment is correct and the
aiming black is set on top of the front sight post so the post just touches the
six o'clock position of the aiming black. The sights are adjusted for the bullet
to hit the center of the target (See Figure 6). This gives the shooter a defined
aiming point. For an experienced shooter, it is the best. For a new shooter,it
causes a problem that will be discussed in the section on FOCUS.

The "Center" or "Navy"
hold is shown in Figure 7. Again, the sight alignment is correct and the top of
the front sight post is placed in the "Center of Mass" of the aiming black. The
sights are adjusted so the strike of the bullet is set to "Point of Aim, Point
of Impact

I knew of a "Sub-Six
Hold," but never used it until a particular weekend. We were shooting the Marine
Corps Western Division Matches. After one week of school and three weeks of
practice, getting ready for one week of matches, I was ready for a break. The
local club was having a rifle match that weekend and the Major said, "You
will shoot and you will have fun."
Every time I fired a
Division Match, I checked out two M-14's, one as a back up gun in case something
went wrong with the number one gun. This weekend both rifles were in for repairs
so I drew a third rifle from the Armory and with no zero, went to shoot the
match on Saturday morning. While zeroing the rifle from two hundred yards in the
off-hand position (you can do things like that when you are a little show off),
my first sighter was extremely high. I ran the sights all the way down to the
bottom and took the second sighter. Again it was way high, but still within the
scoring rings.
In the old days, you
were allowed only two sighters at each yard line (two sighters at the 200 yard
line for both off-hand and 200 yard rapid). Since then, a new rule change allows
two sighters at each stage (two for off-hand and two for 200 rapid). I decided
to use a sub-six hold, shoot the twenty shots off-hand, have the armorer put on
a new sight, and re-zero for the sitting rapid stage.
Using proper sight
alignment, I used the bottom edge of the 4' x 6' target as the aiming point and
had the sights set to hit center. To my amazement, I found I could call my
shots. I could tell if the shot was going to be just out of the ten ring at
three o'clock.
For a period of time, I
experimented with a sub-six hold (not that much of a sub-six hold). I
held about one half the way from the bottom of the black to the bottom of the
target and had the sights set to hit center, while maintaining proper sight
alignment (See Figure 8). I found the sub-six hold allowed me to

"accept my wobble area"
and continue the squeeze of the trigger without trying to make the shot "too"
perfect as in the six o'clock hold. A slight call to the right still gave me a
ten at three o'clock and a slight call high still gave me a ten at 12 o'clock.
The center hold works much the same.
Jack Krieger, an
excellent Long Range
shooter and well known rifle barrel maker, holds the world's record for a
sub-six hold. We were shooting a 1,000 yard match and he brought a different
rifle on the second day, but forgot to bring his sights. After asking around, he
found an extra set that would fit his rifle. He took his first sighter and I saw
it got half way up the side of the mountain (all right, large hill). He came all
the way down to zero on the sights and still was way over the target at 1,000
yards. I had him hold on a trash can at the 600 yard line and shoot again and he
was still over the target. He then held on a clump of dirt on the 800 yard line
and his shot was low and left. I brought him up and right and we got onto paper
. . . he fired a 193 with a sight picture 800 yards sub-six.
Some people use a "Line
of White" hold or a "Flat Tire" hold. In the "Line of White" hold you hold just
a little under the six o'clock position so there is a line of white between your
front sight post and the aiming black. The "Flat Tire" hold has you pushing your
front sight post up into the aiming black a little so that the round aiming
black appears to have a "flat tire." The problem with each of these is "How
much?" and keeping each shot consistent.
A "Frame" hold is used
in very poor light or in foggy conditions. You can barely make out the target so
you shoot for the center of the frame, because the frame is all you can see.
All these sight
pictures work. I have used each from time to time and I've changed around. I
have practiced for weeks with a sub-six hold and the morning of the match
decided to go with a center hold because it felt right.
ATTENTION!
ATTENTION!!
ATTENTION!!!
Put the book down and go
take a break! Come back later when you are refreshed and can give the next
section your full and undivided attention. It is so important, it will
dramatically increase your scores and/or classification.
FOCUS
I read an article on sight
alignment, and it was pretty good, but I waited to see what they had to say
about the focus. Near the end of the four or five page article was one small
paragraph where they stated, "The proper focus is on the front sight post and
not on the aiming black." That is true as far as it goes. When I started
shooting High Power in 1965, I was told the same thing, but how important
the focus is was not driven home.
When I started shooting, I
was pretty good in the off-hand position. My rapid fire strings were OK, but my
600 yard scores were terrible. I had elevation problems you wouldn't believe. I
tried everything, six o'clock hold, center hold, sub-six hold, line of
white hold, flat tire hold, frame hold. I held the bottom of the target. I held
the top of the berm and nothing helped. I could not hold elevation well enough
to keep the shots in the black, much less the ten ring. I changed one thing -
my focus!! My elevation at 600 yards dropped to X-ring size and I went from
getting bronze medals to silver and gold medals. My scores and classification
shot up. I am now a "reformed non-focuser" and will talk to anyone who will
listen.
During my advanced class
in High Power, I show a series of color slides, about 15 of them on rapid fire
groups. Each group is different and there is a reason the group is the way it
is. I show each slide twice. The first time I put the slide up for about 15-20
seconds without saying anything. The student looks at each group and tries to
recognize his or her groups. The second time, we talk about what causes the
group, and how to correct it.

The first time I ran this
part of the class, I was running through the first set. When we came to the
slide that looks like Figure 9, about 75% of the faces in the audience lit up. I
said, "Oh, you recognize your group." The second time I gave that class, we had
close to 100 people, and again, about 75% of the faces lit up.
The cause of having a
group like that is, improper focus. There is a second reason and I will
cover it in that section.
AN EXPERIMENT
With the sun or a strong
light behind and above your shoulders, put your right hand at arm's length and
down at a 45 degree angle with your index finger extended and the fingerprints
facing you. Place your left elbow against your side and place your left hand in
front of your body. (This gives the proper distance between fingers). Again
extend the index finger with the print facing you. Make sure the finger on your
left hand does not block the view of the finger on the right hand. The two
fingers should be close together in the line of sight, positioned so you can see
both at the same time. The fingers should be 10-12 inches apart.
Focus your vision on the
finger closest to you until you can see the finger prints. You can still
see the other finger, but you cannot see the prints. Shift your focus to
the finger on the right hand and focus on the prints; you can still see the
other finger, but you cannot see the prints. THE HUMAN EYE CANNOT FOCUS ON TWO
OBJECTS AT DIFFERENT DISTANCES AT THE SAME TIME!!!
You can rapidly shift your
focus from one finger to the other and convince yourself you are focusing on
both -- YOU ARE NOT.
Another example, as you
are watching a movie or TV program, the camera is focused on the person standing
closest to it and the image is sharp and clear. The person standing in the
distance (3 or 4 feet away) is blurred - you can see hem but they are not clear.
The cameraman changes the focus as the other person starts to speak, that person
becomes clear and you see the one nearest the camera start to go out of focus.
Because of the distance, the camera, like the human eye, cannot focus on the two
objects at the same time. They can be seen but not focused.
Let's apply this to shooting.
In the aiming process, we
start with your eye. I have already covered eye relief, keeping the eye the same
distance from the rear sight each time. The ideal situation calls for your head
to be erect and you looking straight through the rear sight, but, due to the
different positions, this is not always possible. Your head may be down and you
are looking through the top portion of your glasses.
Most people recommend you
shoot with both eyes open. They say closing the left eye puts a strain on the
right eye. After awhile, you get a slight quiver in the muscles around the eye.
I tried shooting with both eyes open and did just as well as with one eye
closed. It felt so strange that it bothered me. (Thirty year habits are hard to
break.)
The line of sight goes
from the eye, through the rear sight aperture (the mind forms the imaginary
cross hairs). The front sight post is then brought into the line of sight and
correctly aligned with the imaginary cross hairs. By placing the aiming black in
the final stages of the process, and forming the sight picture, you have the
process taught to most people.
Little or no attention is
given to the proper focus. The front sight post is the proper place to focus and
is critical to good shooting and scores. Picture the front sight post as the
finger closes to you and the aiming black as the finger furthest away. Even if
it is 200 yards, 300 yards or 600 yards, you must always focus on the
front sight post!!
Remember I said I had
trouble holding the elevation at 600 yards. Well, after someone told me about
the finger print experiment I tried something. (I'll skip the hard way I took at
the time.) After blackening your sights, take a number two pencil and draw a
diagonal line on your front post. (See Figure 10.) This acts as the finger
prints, and when in focus, will not allow you to focus on the target.

Once I started focusing on
my front sight post, I also went to a "center hold." I put the post into the
aiming black and let my position take over. I did not try to get it absolutely
perfect. You close the bolt, put the rifle into your shoulder, check your number
board, take your breath as you put the front sight post into the black, and
focus on the pencil mark as you squeeze off the shot.
My elevation problems
reduced tremendously. In fact, they came down to almost X-ring size. I could pay
more attention to the wind. I thought, "if this works at 600 yards, it should
work at 300." It did. How about 200 yards - surprise again, it did.
We fired a match at Twenty
Nine Palms, CA. My first ten shots off-hand were all in the black. I had two
tens and eight shots were nines. I realized I had been focusing on the target. I
even remembered seeing the orange scoring disk. After I gave myself a mental
drop kick, I fired the second ten shots, this time focusing on the front
sight post. They were all in the black, eight tens and Xs and two nines.
Changing the focus brought in the wide shots. From that day on I have been like
a reformed alcoholic. I preach focusing to anyone who will listen. Shooting leg
matches, up to that time, I had three bronze medals. After I started focusing, I
got a silver and a gold medal, to go Distinguished.
You can tell if your focus
is correct by your "call." Calling predicts where the shot will be on the
target, based on how your sight alignment and sight picture looked. If you
called it a ten at six, and it is a ten at six, then you are on call. If
you called it a ten at six, and it is a ten at twelve, then you are off call and
you should adjust your sights. A young lady on the Marine Corps Team last year
said it very well, "If your shot is within your call, your focus is
correct. If it is outside your call, your focus is incorrect."
