I took three VZ52 rifles to the range for the first time to check them out with mil-surp 7.62x45 ammo. I was having trouble with failures to fire even though the primer was hit. Then I found that there were two differences in the ammo. Some had what looked like large rifle primers and others had small rifle primers. I had NO problems with the small primer ammo but lots of failures with the larger primer cartridges. Has this been observed by others in their VZ52s?
The other issue is trying to get a cartridge that failed to fire out of the chamber. Once the firing pin is extended into the primer, it remains extended because the hammer is pushing it forward. When I try to manually cycle the action, the bolt carrier is stuck trying to raise the front of the bolt. I'm pretty sure the extended firing pin is keeping the bolt from sliding up out of the locked position. I also noticed that two of my three rifles put a dimple on the back of the cartridge case at the 12:00 postion above the primer. This puzzled me until I realized that was from the firing pin hitting the case a second time as the action cycles.
Getting the unfired cartridges to eject took some major whacking on the bolt carrier handle. I don't like having to do that to a rifle. Is there a better way to eject a bad cartridge?
If I'm right about the firing pin riding on the back of the case, I don't see how the action slides up normally when the cartridge does fire. Is there something I don't understand about the way this action works?
