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
 
I have never heard of this particular problem. I know at one time there was an issue with the mini-30 supposedly unsafe to fire with russian ammo because of slight bullet difference (how much of this was hype, I'm not sure). But your particular problem I havent ran across before, so it probably isnt common.
 
My used Mini 30 was built around '03-'04 and went through about 2,000 rds. of only Russian ammo.

It had a FTF now and then, but never suffered a broken part.
