[QUOTE="freddiej, post: 1846437, member: 26227"] From your pics I would say this to you: #1, your head spacing is very good. no sharp corners on your primers showing excessive headspace. #2, slower burning powders can cause the flow back you see on your primers. I have this on my 17 Rem when I was using standard winchester or remington primers. only BR primers would not flow back. #3, stop using 57 grains of powder. the harmonics are bad at that grainage. #4, I would use any grainage between 53 and 56 grains if they all shoot 1" groups. #5, check your breechface for heavy brass wash and stop using any load that has excessively heavy bolt lift. have fun.
