RE: Sighting Rifles
I fire a shot at 25 yards to hit the center dead on then take a three shot group at 100 yards. The next part works best if you can lock down the gun. With the gun locked in position, crosshairs on the point of aim, with out moving the gun adjust the cross hairs below the point of impact that you want your bullets to strike the target. IE: cross hairs two inches lower than the group will put you two inches high. You should be sighted in but shoot another group to make sure.
