Okay you guys. What do you think’s happening here: Ruger MkIII 22/45, 4.5” barrel, standard sights, 7” paper plates with ¾” round colored stickers in the center, just over 20 feet, ten rounds per plate, all rounds CCI Mini Mags. 1) Both hands, Weaver stance, hits all over the plate; 2) Strong hand, bulls eye, hits all over the plate, but tighter; 3) Weak hand, bulls eye, hits all over the plate; 4) Both hands, Weaver stance again, first seven shots, 1” group, 3 shots touching the sticker, 1 shot dead center, 8th shot opens up to 1 & 1/4”, 9th shot opens up to 1 & 7/8ths", 10th shot hits on edge of plate. What do you think is going on? Besides not shooting the first 30 rounds and the last three, anybody have any other ideas?
