Absolutely correct. And given that the Center of Mass is a large
verticle zone, Point Blank range is a pretty good distance, where
you dont have to hold over..you simply need to be able to place a
round in that area.
Hold at the top of the COM, and for quite a number of yards going
farther and farther away, a round fired will go into that verticle
area.

Which is why I keep my '06 zeroed at 350 yards - with my normal loads
that provides me with no more than a 3" vertical variance (plus or
minus) out to about 450 yards.

After that, the drop accellerates and the kinetic energy diminishes
rather rapidly.

Depending on the bullet and the velocity of course, with a 350 yrd
zero, your point blank range should keep your round inside the COM out
to about 625 yrds. The 175gr International type bullet at 2750fps has
some legs and at 625 yrds, should still have more energy than a 44mag
at the muzzle.

Yabut the COM on small varmints is fairly small, thus the shorter
distances... G


Two legged varmints, or the 4 legged kind?

his flashlight on a barn rat, Joe has aimed his 45. Caption: "Aim
between the eyes, Joe, they some times charge when wounded."
