I shot again with 140 Bergers and imr4451. Just started to see faint ejector marks at 49gr with lapua brass and a speed of 3140. Accuracy was sub moa for 5 shots. Backed down to 48grs with a speed of 3120 and sub moa accuracy for 5 shots. I think I might back it off another grain. Should put me right at 3100 then mess with seating depth to fine tune accuracy. I would like to see it produce 1/2" 5 shot groups @ 100yds. I know it's capable. During fire forming of the lapua brass it put 8 out of 10 shots into a sub 1/2" group.
