Bad batch of bad firing pin.

[Aaryq]

Howdy folks. I have a question for you. A while ago I purchased about 80 rounds of Olympic 180 gr 7.62x54R. I've shot about 40 rounds of it prior to my adventure today and every time I pulled the trigger, it went bang. I took it and my mosin to the range with my buddy to show him the joys of Mosin Shooting. I brought 20 rounds of the Olympic that I bought. We fired of 20 rounds...I take that back. We pulled the trigger 20 times. The gun only went bang 8 times. The primers were dented but it was a failure to fire. Is it my Firing pin that's jacked or just a bad batch of ammo?

Have you checked the firing pin protrusion on your MN?

That is typical Olympic quality, at least yours looked like ammo. I have never heard of more confirmed QC issues than with Oly Ammo.

I had a few boxes, 15% had backwards primers. Seriously, they couldn't pay a Turkish kid $1 a day to look for backwards primers?

Here's how to set the depth on your firing pin. If there was a decent dimple on the primer, then it could be a bad batch.

Olympic blows.

Your misfires could also be due to excessive headspace.
