K98 wont shoot surplus ammo

[Han]

Hi everyone I have a k98 and two crates of 1950s Yugo 8mm surplus ammo, and the rifle only shoots about in in 5 bullets. My CZ mauser shoots the ammo just fine, although looking at the ammo there are a lot of very deep set primers. I have put in a new firing pin and a new spring, no difference. Firing tip protrusion is fine. Any suggestions and advice would be much appreciated!

Perhaps post photos comparing primers struck by the K98 and the CZ.

We had a rifle here with the same problem. The bolt shroud was not screwed in all the way.

What he said.

Disassemble bolt,clean properly and reassemble.

In my surplus I found a lot of caked-on cosmo/grease/dirt accumulated in crevices,especially inside bolt body where it interferes with proper action of firing pin.

What is the firing pin protrusion?

Lot of guys have this issue and buy stronger firing pin springs.

Just send a crate of that ammo my way and I will test it in my K98!

Try another complete K98 bolt and see what happens.

Check Headspace?

I have a couple rifles here also , and would be willing to help with the test.

You say you added a new spring. Was it a 28 pound spring, or more? That is what milsurp ammo needs to shoot reliably.

Primers ignite from the shock, not the energy. Important that the bolt internals are clean.

Is it a matching bolt? If bolt is too short, the protrusion may be insufficient, but headspace would be bad.

Ditto on what everyone else said. Also, 1950's Yugo 8mm have deep set and very HARD primers.

Thanks for all the replies everyone, I purchased a new firing pin and spring will try it out this weekend and post results.
