M24/47 bolt won't close on 8X57 Romanian surplus ammo

[KKsan]

Hi guys I recently got a M24/47 Yugo Mauser in unissued condition. The gun is really in good shape. Today I finally got some Romanian surplus 8X57 JS Mauser ammo (Lacquered steel case berdan primed 170 Gr FMJ ball).

I tried to feed it by directly resting one single round in front of bolt face and close the bolt, result: bolt can't be fully closed (it stays at 45 degrees). Seems that the bolt doesn't go forward fully. I didn't dare to force it.

I then tried putting rounds into the magazine well, let the spring to raise the round up, and close the bolt. Same result.

Based on my observation, the bolt extractor can extract the round just fine. But the bolt can not be fully pushed forward.

To fully rule out the issue on the rifle itself, I just ordered some snap caps in 8x57.

But before I can test it again with the snap caps, could anyone give me some words of wisdom? Did you encounter this issue? Ammo issue? Bolt issue? Possible fix? If the snap cap fails again, I'll bring the gun to a gunsmith.

Maybe a headspacing issue? I doubt it's the ammo, I've used that in my K98 before and it was fine, although I suppose there could be a slight chance of a bad lot.

Anyone else you know have a 24/47? You could try the ammo in their rifle to eliminate the ammo as a cause. Could borrow their bolt, use it on your rifle and see if the round would chamber with a different bolt too.

Thank you for your input!

The ammo is advertised as .323 S bore. I searched online and everyone suggests M24/47 is compatible with it. I'll try the snap cap once it arrives. Unfortunately I don't know anyone around with a Yugo Mauser.

If the ammo head stamp says "SADU 13", it's out of spec from the factory. Stick the bullet in the muzzle. If it goes all the way in, you got ammo from the bad lot imported a few years ago.

Holy **** all the ammo has SADU 13 on it


Can I sue Sportsmans guide for false advertising lol?

How recent did you buy it from them?
Both them, and Cheaper than Dirt, know about it and were refunding the buyers money.

Learn something new every day, I hadn't heard of a bad lot of Romy 8mm before now. Sucks it's an ammo issue, but at least it isn't the rifle.

I bought it over blackfriday last week. I'll try contacting the website customer service.

Looks like your immediate question is solved, but for future reference load the ammo into the magazine first & let the bolt pick up the round.

Things learned! Thank you sir.

Mausers are control feed. For the love of god, do NOT put a round in the chamber and try to close the bolt. You *will* eff up your extractor. Push feed can single load like that, but not control feed. Google for details.



Let us know if Sportsman refunds you.

FWIW, I have some 'SADU 13' ammo that I bought a couple years ago at a gun show. It functions in my M48BO with no problem. I guess I got lucky.

Yep definitely a lesson learned.

That is not "surplus", it is new production, supposedly made to the same specs as the real surplus that dried up ~5 years ago.
