Muzzle Movement, Bullet Deflection, And Gunfight Accuracy
.
When shooting, small amounts of muzzle movement can
significantly affect accuracy. The table below, shows the
amount of bullet deflection at various distances that will
occur with various amounts of muzzle movement.
Bullet Deflection With Muzzle Movement
Distances --- Bullet deflection with muzzle movement of:
____________1/8in___2/8in___3/8in____4/8in___5/8in
____5ft_______1in_____2in_____3in_____4in_____5in
___10ft_______2in_____4in_____6in_____8in____10in
___15ft_______3in_____6in_____9in____12in____15in
___20ft_______4in_____8in____12in____16in____20in
___25ft_______5in____10in____15in____20in____25in
Example: If your gun muzzle is just 3/8in off from the exact
center of a chest sized target (11in wide x 17in tall), and you
are at a distance of only 15 feet, you will miss.
If you consider the table data, trigger resistance,
recoil forces when shooting, and the conditions that
are experienced in close quarters shooting situations,
it is clear why close quarters shooting accuracy is
as bad as it is.
In the 100+ years since the modern pistol came into use,
gun makers, experts, and trainers, have yet to come up
with a practical means and method for quick and accurate
shooting that can be taught and which works in real time
close quarters shooting situations.
As such, it is no wonder that you get shoot first and ask
questions later situations and hair-trigger-ready-to-shoot
situations with their tragic consequences that can cost
millions to settle, and much more in terms of lives lost,
careers ruined, and loss of respect for Law and order.
Those who write about gunfights as authorities, say that
in close quarters shooting situations, instincts come into
play and training often times goes out the window.
That thought is supported by news accounts of shootings
that I have read, and TV films of real time shootings I have
seen. Two things are common to almost all of them, first,
accuracy is very poor, and second, most shooters fire rapidly.
In the past 40 years, I have seen as a spectator two real
time shootings where shots were fired rapidly and where no
one was hit.
It is quixotic and oxymoronic to me that handguns which are
used for self protection in life and death close quarters
shooting situations, do not have a ready and reliable means
for accurately shooting them in those situations.
Here's How The Table Values Were Determined:
1. The values are actual values, or very close approximations.
2. The circumference of a series of circles was determined
using the table distances as radii.
3. The circumferences were halved to get the lengths of 180
degree arcs that correspondeded to the distances.
4. The muzzle point was considered to be 7 inches out from
zero, and the length of a 180 degree arc with a 7 inch
radius was determined.
By chance, each degree of that arc equals 1/8in. Inches
in eighths instead of degrees were used on top of the
muzzle movement columns for ease of understanding.
5. The muzzel movement amounts expressed as percentages
of the 180 degree arcs, (1/180, 2/180, 3/180 4/180, 5/180),
were applied to the arc lengths get the deflection amounts.
6. Because an arc is a curve rather than a line, the deflection
amounts shown are approximate values. However, they
are very close to the exact deflection amounts because
the arcs at the distances shown, are very large relative to
the deflection amounts.
You also can use a metal tape measure to check out the table.
1. Pull out ten feet of tape and lock it. Then place the edge
of the tape on a straight line on a floor that is formed by
the edges of boards, where floor tiles meet, etc.. You may
need to tap it a bit so it will form a straight line.
2. Mark the floor at 10 feet, and at 7 inches out from that mark.
At the 7 inch mark, make marks at 1/8, 1/4, 3/8, and 1/2
inches away from the line and on the left side of the line.
3. Using the 10 foot mark of the tape as your starting point,
keep that point on the line and move the tape off the line
so that it will be on the 1/8th inch mark . You may need
to tap the tape a bit again.
4. The edge of the 5 foot mark on the tape will be 1 inch off
line, and the edge of the start of the tape will be 2 inches
off line.
5. Other table values can be checked in the same manner.
The table shows why most gunfights take place at distances
under thirty feet. Only the exceptionally good shooter would
be able to shoot well enough to hit a chest sized target at a
distance beyond 30 feet.
That means that your safest course of action is to get away,
run away, or otherwise disappear fast and quick if you can.
The table also shows that handguns can be very effective at
close range. I recently saw an old TV clip of real executions
in which handguns were used. Three people with their hands
tied behind them, were brought into an open area of a city
square. They were shoved down onto their knees, and killed
with one quick shot to the head from three to five feet away.
Each one was killed by a different shooter.
Unless there is a need to restrain a person directly, there is
no reason to have a gun up close to a person. Up to a
distance of 5 feet, the muzzel would have to be more than an
inch off the target center for you to miss a chest shot. Also
if the person is about five feet away, there will be less of a
chance that the person will grab your gun or attack you.
The table also shows that it makes sense to turn sideways
to an adversary in a shooting situation. If you are half as
thick as you are wide, and you turn sideways, your chance
of being shot will be reduced by 50 percent.
Why give your adversary the largest possible target when he
or she is trying to kill you? Why not turn sideways and then
shoot if needed.
The table also indicates that if you turn sideways, you will be
next to invisible to an adversary at distances beyond 10 feet.
That is unless he or she is an exceptionally good shooter
who can keep the gun muzzle within 1/8 inch of the exact
center of your slim silhouette, or has a gun with a P&S Index
Finger Rest, or it is unfortunately, a most unlucky day for you.
I am a proponent of Point & Shoot and the P&S Index Finger
Rest. They provide the method and means for fast, accurate,
and instinctive shooting at day or night in close quarters.
