Is there a sharp point on your firing pin?

I thought someone else would have come along by now. Is this an SKS? Is your firing pin worn? Maybe sticks out of the bolt too far? Just thinking that it is probably your rifle since it is two diferent manufacturers. These are factory loads right?

Top pic, top left looks exactly like a pierced primer. I would say you got an out of spec bolt or firing pin. Looks like too much firing pin protrusion. Maybe broken firing pin. Have you examined the firing pin outside the bolt??

Pics of the bolt face with you pressing the firing pin in by hand would help

+1, what he said ^^^^. Check the bolt face and firing pin. AKs are built for Berdan primers, an out of spec bolt or firing pin could be striking the Boxer primer with too much force.
