Shooters that
win usually check
their guns and
ammunition for
accuracy and a basic
zero off the bench.

S

ighting-in a rifle whether for plinking,
hunting or competition is not all that
hard. However, there are some "tricks
and techniques" that will help it go better.
There is a difference between testing for
accuracy (shooting groups) and sighting-in
to get a correct zero. Let's not mix them up.
Accuracy testing obviously checks rifle and
ammunition accuracy by shooting groups. This
is easily resolved-simply have an aiming point
on a target or a sheet of paper (such as butcher
paper with a sticky note on it). Then, shoot your
test groups and at this time do not sweat where
they hit-if you want to check for accuracy
through grouping. If you shoot up your aiming
point, you have simply lost your target.
It's simple, once a certain ammunition mix
groups best for you, the zeroing process
begins. Take the group you most prefer, and
note the distance from your target's aiming
point. Make sight adjustments to move it where
you wish your rounds to hit-and of course
verify your adjustments with a few shots. That
was easy-but wait, there's more.

Let's talk ammunition. It can make a big
difference! If you are hunting and your game
is within 200 yards it will not matter as much if
your game is out 300- to 600-plus yards. A rifle
that keeps shots in a 1-inch circle at 100 yards
will generally not keep them in a 6-inch circle
at 600 yards. Rifles are not lasers or photon
torpedoes-the bullet strike to range minute of
angle (MOA) is not proportional.
If you have a rifle that groups an inch at
100 yards and keeps them in 6 inches at 600
yards you have a great rifle and you are a
very good shot too! Yes, I know, there are a
bunch of half minute guns out there that will
hold 3 inches at 600 yards if the ammunition
is really accurate and a true expert shooter is
involved-however, both shooters and guns
that can do that are rare.
Keep your ammunition cool and out of direct
sun at the range. Cartridges laid on the bench
in direct sunlight will heat very quickly, which
raises internal pressures when fired. These sun
heated rounds will develop higher random
pressures from round to round which alters
