I'm having a problem with my Tokarev clone, Norinco T-54, piercing primers. I thought there might be several reason for it, so I've tried to narrow it down. I've checked head-space, and that comes up good.The firing pin looks to be intact, with no burrs on it. I'm beginning to suspect the pin might be too pointed, or the hammer is driving it a bit to aggressively. One thing that strikes me as odd is it looks as if the pin is still in contact with the primer when the barrel unlocks and shifts downward during slide and barrel recoil.
It might just be that the primers are just a little too soft for this particular gun. I'd appreciate any input on what might be needed to correct this problem.
I've attached some photos of brass that has been through it, as well as a piece of brass from my .vz52.
