Almost
every pro 3-gun shooter I have talked with brought this up: how
critical it is to know where your rifle hits at any distance.
So
many shooters zero their gun at 50 or 100 yards and think they can rely
on a computer program or ballistic chart or what their buddies tell
them for the rest, but that will not work. You must absolutely know
where your rifle will strike at any distance from 5 yards to 500 yards.
It’s not just the long shots where this is important. A lot of shooters
try head shots at ten yards, and with the offset on the optics, hit the
hostage target below. You must shoot your rifle at every distance and
know, with the certainty that only bullet holes in the target can
provide, where you will hit at any given distance.
