this is from the other day at 100 yards sighting in and using Winchester Super X 180 grain ammo . I just put (6) rounds on this target that i modified so i could use less ammo to sight in , The target is gridded off in 1/4" moa so i could walk the rounds quickly into the bullseye . as you can see rds # 2,3 impacts are only 0.577 inches apart and the bullseye is 0.185 inches off from being dead center of the bullseye ,rds #5 & 6 were flyers do to very strong gusts of wind that came up and stopped shooting after that
