Those primers look very flat, and the fact that so many of them were blown completely out tells me that your probably past safe headspace. I would definitly take it to a gunsmith and have the headspace checked. The surplus military ammo will have harder primers and they are probably swaged in like american military primers. That will help hold them in, but that is still a sign of high chamber pressures and could cause major safety issues. I would never shoot a gun that was blowing primers like that until I had tracked down the reason for it with absolute certainty. That gun could hurt a shooter or bystander, please get it fixed before you shoot it again.

Ok I'm going to try and be gentle here. If you don't know what headspace is you should not be taking guns apart. Headspace is simply put the given tolerances for room around the cartridge in the chamber. Not enough and the gun can go kaboom at worst. Too much and at worst the same. Firing a gun that is not properly headspaced is extremely dangerous. That said headspacing is generally not an issue with the ak and sks. With the sks the issues generally revolve around the firing pin. You likely have too much protrusion. I suggest you get a spring loaded firing pin to avoid the other typical sks firing pin related issues of slam fires and going full auto due to the firing pin getting stuck in the forward position.

I can strip it completely & have it back together before u make ur morning coffee. Just because I don't know a technical term doesn't mean I don't half azz know what I'm doing. Ijs.... But thanks for the info, I learn something new everyday.

Knowing what headspace is is part of the basics. Don't bite off more than you can chew that's how you get hurt or killed. Trying to assess a primer issue like that and not knowing anything about headspace doesn't work. You got lucky this time. I hope if you took a file to your firing pin that you did it correctly and didn't leave any sharp edges. Just because you can strip one of the simplest rifles in existence doesn't mean you know enough to be reshaping a firing pin.

That's why we ask questions, to learn. But there's always someone that talks out of there azz & all that comes out their mouth is ****, when all they could have done was answer the question to help someone instead of being a smart ass. Btw, its fixed already.
