Primer puncturing in gun....

This is kind of a continuation of the "Barrel Shot" topic that totally evolved when found out more data. Turned out the primers were being punctured, but he sent the gun to a gunsmith, so the topic ended. But I think some serious safety issues need to be descussed about this problem, and I have some questions myself.
One main reason I can think of that your gun could be puncturing primers in factory loads, if in all loads, is that the firing pin really needs to be replaced. It may be sharp, warped out, or to long. There are guages for measuring to see if the firing pin is comming out to far, but firing pins are so cheap that its probably best just to replace it, if that fixed the problem fine, if not, then you should send your gun to a gunsmith.
Now I have a question. A buddy has an SKS, and when he uses wolf brand ammo it works perfectly fine. However whenever he uses American Eagle ammo, he has problems with the primers getting punctured. The only thing I can think of is that the two different ammunitions have two different seating depths on their primers. Not only that but also wolf ammo is berdain primed so the anvil would be facing the opposite side. I've been trying to convince him to replace the firing pin, and/or send it to a gunsmith, but he wont since it works fine with the wolf ammo. Also, the gun is a Norinco SKS. Has anyone else ever had this problem in a Norinco SKS, and what was the cause. Any scare tactics I could use to get him to check the darn thing out before he has an accident and blowes himself up?

Take the firing pin out and examine it for roughness. Polish off roughness and sharp edges with a fine handstone. If firing pin protrusion exceeds .055, dress it down to about .050".
