Mislabeled 8mm Mauser ammo?

>>32584080
OK, I think I follow. You think the ammo you bought isn't really 8mm Mauser? If that's the case, send it back.

Are you sure your gun is 8mm?

>>32584080
It's possibly been rebarreled or simply rechambered. Happened a lot to old Mausers especially in government hands. There's a whole shitload of Mausers converted to fire 308. I'd suggest having a cast made of the chamber to compare its dimensions and ensure you fire the correct cartridge. It's actually pretty important to check. I'd have blown up my grandfather's M1 Carbine if I hadn't realized it was chambered in a 22 wildcat instead of 30 Carbine.

Ammo on the left chambered and fired fine, but the ammo on the left is the ammo that won't chamber fully. The ammo on the left is in fact 8mm Mauser ammo.

>>32584080
The ammo you bought will not chamber in most mausers from what I have seen. .323 bore diameter is correct for your mauser, but the cases are too long for the cartridge to chamber.
Romanian, turkish, and yugo surplus, or european commercial ammo will work.
American 8mm mauser is garbage.

SADU should be Romanian, though. But I've only ever gotten SADU 7.62, so I might just be talking out of my fucking ass anyway.

If it is what I think it is, it's Romanian ammo manufactured in 2012, which is odd because that should fit perfect.

You got a micrometer, OP?

Also, KSP. Fucking ace choice.

Thanks broski

It was manufactured in 2013. No I don't have a micrometer, but I'm trying to figure out what I can do. From here it looks like I'll have to
1) swallow the money I spent and deal with it
2) try to get my money back, although that seems unlikely
3) modify the rifle to fire this ammo, which kinda sounds like a bad idea.

I'm confused, wasn't JS ammo the WW2 standard? If so, why does that ammo say non-ww2? And if not, what the hell is JS?

Holy shit, I thought JS was the standard and you didn't need to worry about it unless you were shooting pre-WW1 stuff. Now i'm afraid to buy 8mm ever again.

>>32584710
Well don't buy 8mm ammo from Sportsman's Guide.

>>32584743

Yeah I would think it's just a mislabeled ad except even the sample cartridge box it shows is labeled JS, so I'm not really sure how they could fuck that up and ship non-JS ammo when the ammo is clearly marked as JS. It's not like Sportsman's Guide could have swapped out the bullets in the box. I assume the box OP received also said JS. So I'm not sure how it could possibly be non-JS, unless the factory fucked up.

Here's a picture of the case, if it helps.

>>32584808

Yeah, as far as I can figure that should be JS ammo and your rifle should shoot JS ammo. The questions that remain are why it didn't fit in your rifle, and why that Sportsmans Guide page lists it as "non ww2 dimensions."

All I can suggest if you don't have a micrometer is go to a gun store and find a box of modern production 8mm, probably PPU or Hotshot, and see if those chamber. If they do then the problem is with the Romanian ammo, if not the problem is with the rifle.

Hope you fix it fast you jew.

OP that romanian stuff is so much hotter than SAAMI loaded 8mm.
Before even trying to chamber it, confirm that your turk mauser is a large ring, long action mauser.

Hey I know this Italian.

I have shot both out of my 1915 Spandau Gew. 98. Works fine

Anon here who loves this stuff to death, I want to let you know it works. You just have to really REALLY not be a bitch with your bolt. The casing necks are just a tad bit too long, and because of the wax laquer you really have to close the bolt on it.

My Zastava M98/48 takes a lot of effort to close on it, but my brother's Turkish Mauser eats it right up with no problems.

Good luck anon, and hope this helps, it shoots just fine once you close the bolt.

It's because this stuff is romanian, and the neck is a little longer than the ww2 spec

Are you sure about that? I don't wanna screw up my bolt or damage any innerworkings

>>32586421
Yes, positive. Mauser actions are built really tough, and I would have found out the hard way by now if it didn't work. Trust me, it takes a bit to get it closed though.

>>32586450
Yea I managed to lock the bolt down once, but it really took a bit of effort and it freaked me out a bit.

>>32586460
It should go fine as long as your gun is chambered for 8mm. Now as for that, I can't assure you. But this ammo works, and it works great.

It's machine-gun ammo, you can fire it from regular bolt rifles but it's not recommended - it's hotter.

>>32586494
Is it any less accurate?

Someone hand this man a mosin so he can learn the ways

>>32586502
No, just the same or slightly better.
It's stock from a military contract that fell trough and has ended up on the civilian market instead of being destroyed.

Yea I'm not super familiar with guns, but being an engineering student makes you cautious around forcing mechanisms shut like that.

>>32586553
The forces in that are nothing compared with the forces generated when you fire that cartridge, stop worrying for nothing.

>>32586460
It's not your rifle, its the ammo - not manufactured to proper headspace. If your bolt closes on it, its safe to shoot, but rifles with tight headspace will have a hard time closing or not close at all. Beating the bolt closed on a couple hundred rounds may not be the best idea.

Its too bad more people arent into reloading, you could break it down into components and even take the decapping rod out of your sizing die and bump the shoulders down to get a firing out of those primers/cases.
