I'm having some issues with a bullet in a rifle I have a lot of time shooting, and can shoot very well with my known loads (175smk). When trying out the 178 amax and shooting for groups, I can occasionally get some sub 1" 5rd groups at 100yds, but usually 3-4 of the rounds are well under an inch with 1-2 fliers 1-2" out making almost all the groups 1.5-2" total. 10 round groups usually have 7 rds under 1" with 3 fliers opening the group up to the same 1.5-2" size.
Is this a sign that my rifle is not completely stabilizing the bullets, or would it show no kind of group if that was the case? How can I tell if I am having stabilization issues? Am I just overlooking something here?
FWIW, my rifle is a 16" .308 gas gun, 1/11.25" twist rate. I've almost always shot the 175smk, but decided to try the 178amax and got these results. I am almost 100% confident that the issue is not me because I can swap to my good 175 load, or drop in my 6.5cm barrel and easily shoot sub moa groups.
