well I think I have resolved my piercing primer issue,went to the range today with the same load and bullet,except this time I used cci BR4 primers wich are .004 thicker,went through 20 rounds and no pierced primers.the only thing that was a lil different was,using cci BR 4 small rifle primers and new winchester brass,my p.o.a. was 4'' left nad 2'' high,but grouping was excellent as it was before.Now I should also mentioned I bumped my rifle a week ago and maybe my scope got knocked out a bit,but it wasn't that big of a bump,or does changing brass and primer affect poa that much???.bottom line is no more piercing primers..
