8 Round stripper clips sounds czech... what's the headstamp?
Czech surplus gave me lots of misfires and it was a waste of time. My tokarev has digested dozens of unspeakably bad condition bulgarian rounds with no problem, one with small cracks by the hundreds. I'd had one round that was split halfway down the case that jammed when it cycled into the pistol: I pulled it out and it was curved like a banana. I pulled the bullet out with a pair of leatherman pliers with very light pressure. Only one i didn't shoot, i'll probably dump the powder in the garden, shoot off the primer, and keep the almost unblemished bullet as a momento.
