Bad 8mm Ammo?

Shot some of it today, or tried after finding at a local shop of mine. I haven't found ammo for my Mauser in some time, and so I figured I would try it. Non-corosive, but I'd never buy that!

Well, none of the rounds went off. Maybe 5 out of 45 rounds went off on first hit. I had to reload them back into the chamber another time for them to go off. After the first strike, I checked each primer, and a nice dent was there, but no boom.

Bad ammo, or bad gun? I just had a smith check her over last year and they said it was fine.

Sounds like 1950's dated Yugo 8mm. The primers on this ammo are very hard. I changed the firing pin springs in several of my mausers with Wolff 24 lb springs and now they work pretty good with that ammo. Until I changed the springs my success with that ammo mirrored yours.

Seemed really hard. Made me nervous as hell having to take each round out and reload with a primer that looks like it was hit just fine.

How do you replace this spring?

Do you know how to field strip a mauser bolt?

It's the big spring on the firing pin / striker assembly.

Primers too hard to be fired by a Mauser 98 are really too hard. Thanks for letting us know what to avoid in the 8mm ammo line.

Saw this a lot a few years ago on surplusrifleforum.com, GD is right, change your firing pin spring and you should be GTG.

I have a ton of 50's Yugo that has a failure to fire rate of like 1 in every 15 or so. My 24/47 has a little 'slot' on the rear of the bolt. It so happens that the rim of one of the 8mm cases fits perfectly in that slot and can be used to re-cock it, without opening the bolt. Almost like it was put there for a purpose ;-)

Much safer I think that working the bolt handle and opening/closing it. Using the recocking notch keeps the bolt closed and the round in the chamber.
