I have a 30-06 built by Penrod. It has a Krieger barrel that is 1-12 twist. I am shooting nosler 165 bt. So far I have not been able to shoot less than 1" groups at 100 yards. I was hoping for much tighter groups. My Nosler manual shows 1-10" twist for their test barrel. Will the 1-12 barrel shoot 165's as good as a 1-10?
