Will hard primers break Mini 30 firing pin?
Recently I obtained a case of Eastern Block 7.62x39mm ammo to shoot in my Mini 30. Because of their hard primers I have had a lot of misfires. I ordered a Wolff XS hammer spring in order fix this problem, but am now concerned the extra spring power will break the firing pin on the Mini 30. Does anybody have experience with breaking the firing pin on a Mini due to hard primers?
Any ideas would be welcomed.
Good shooting to you, dgang
