CSA Vz58 pierced primers

[BeaverMeat]

Anyone else have issues with TulAmmo or LCW in their '13 proofed CSA Vz.58s? I have had two failures with this ammo. Primer get pierced and blows out my firing pin. First with Tula, then again with LCW today.

MFS and Barnaul have zero issues.

Gun or ammo?

Also, how do you find out if your gun had the oversized gas port?

Haven't had either types of ammo go through my VZ yet. The 300 or so rounds of Romanian surplus has run flawlessly though.

for the oversized gaz port it easy if the brass fly overs 20-30 feet or more you got an oversized ...

I guess the real question is: Should the firing pin fly out of the bolt when a primer is popped?

Is this part of the design to relieve the pressure. Or is my firing pin spring too strong?

Getting tired of replacing my bent firing pin. Good thing I bought a bunch of spare parts

The firing pin flys out of the bolt? That definitely should not be happening. My guess is you are not re-assembling the bolt correctly.

I see what your saying... But the extractor won't function properly unless the pin is placed properly.

Two pierced primers with TulAmmo and L.C.W. and both times the firing pin flew out was damaged. I since replaced the extractor and firing pin.

MFS and Barnaul. Flawless
