Anyone else having problems with primer pockets gas leakage? About 20% of my Hornady 6.5CM brass have loose primer pockets. I experience gas leakage through them and of course circular carbon deposit on bolt face. The worst, it means inconstant speeds leading to reduced accuracy. What are your suggestions guys???
 
Brass is factory ammo I have fired. After preparing it I started priming. Then felt some primers did not resist in letting at all. When I checked bolt face there was clear carbon deposit circle with the size of a primer.
 
Just once fired I assume? If you are using Winchester primers by chance I have had them do it. They are not consistent at all in their diameter. I've had perfect brass seem like it had loose primer pockets from win primers.
 
I have CM brass that has six firings on it that definitely have primer pockets that are not as tight as they were when they were new, but none of them are leaking. I did have one primer/case that burned through at the radius edge of the primer but I think that was a faulty primer. None of my cases are so loose that they will no longer hold a primer and like I was saying, none of them leak.
