Shot some today. Mixed results. The same loads that were fine on pressures two days ago dropped primers out of the cases on 2 of the first 3 shots. I went in and loaded 3 cases with one grain less powder. Pressure was fine, and the group was better! It measures .199 C-T-C! Went in and loaded 15 more with 48 grains powder just touching the lands. Next group was fired by the bench shooter guy, .967? I shot the next group, .647. Then the bench shooter shot a amazing 5 shot group, .357 C-T-C! I fired one more at .305 for 3 shots, then 2 more offhand just for fun. I adjusted my scope after group 3 so I could keep track of shots better. I'm not sure why my groups are so inconsistant, I let my gun cool for a long time between groups, and didn't fire off my groups right in a row. Maybe my brass is at fault?
