7.62x25/.30 Mauser

[Battis]

I bought a box of Hansen Cartridge Company ammo (old box) marked "7.62 (Tokarev) .30 Mauser."
I have a CZ 52 that I load for (and some factory ammo).
From what I'm reading, 7.62x25 and .30 Mauser look the same, but are not the same. Some say that the .30 Mauser can be fired in a CZ 52, but the 7.62x25 cannot be fired in the Mauser C96 (which the .30 Mauser was made for).
The head stamps are: 7.62 TT and what looks like NNY.
I'll shoot them in the CZ 52, but would it be a Bozo NoNo to shoot them in a Mauser C96, even though the box is marked .30 Mauser?

What used to be done was underload the Tokarev cartridges so they would be safe in either Mauser or Tokarev pistols. I'd contact Hansen before I ran them in a 90 - 120+ year old pistol.

I'm pretty sure Hansen is long gone. I don't have a C96 but I read an old post on another forum where a well known gun writer was quoted as saying that the 7.62 and .30 Mauser were interchangeable, which ticked some people off. But, if they underloaded the Tokarev for that reason, then he was technically right. If I did have a C96, I'd only shoot my own reloads to be sure.

"NNY" is the Cyrillic designation for "PPU', (PRVI Partizan in Serbia).

What you have is 7,62x25 Tokerev ammo which will eventually crack a C96 recoil block. Don't know how many you can get away with, some people try to claim they shoot it in Broomhandles all the time, but having replaced a cracked C96 bolt stop myself, I don't believe them.
You can contact PRVI USA and ask the manufacturer.

iirc - the Czech 7.62 is loaded much hotter then the Russian + other 7.62 - all 7.62 + 7.63 is safe in the CZ52 + all seems to function in mine - 7.62 definitely not safe in the Mausers - Czech mil spec Cz52 is loaded to much higher pressure than the commercially sold Czech ammo -

So, I haven't shot any PPU. But I have shot a LOT of S&B 30 Tok ammo, which is also Czech ammo. And it is indeed hot ammo. When shooting some from an older batch at the range a month or so ago I had about 1/4 of the cases crack at the neck, and lots of looks from those standing around me to see what I was shooting that was making the noise.

If it were my C96, I'd find different ammo to shoot. There is some talk that the CZ52 isn't as strong as a TT. I believe the issue was with the barrel, and how the lug was cut. I am not going to speculate on it's strengths other than to say that mine has shot all surplus fine. But when it comes to an older design such as a C96, I'd err on the side of caution.

I load for c96 and feed the same rounds to TT. It is interchangeable in this way.

DO NOT SHOOT HANSEN IN M96! Cracked block in gun I had almost immediately.

Fine in TT33 at 1450 fps. In .30 Mauser stay below 1300 fps.

fwiw - the Czech C52 mil spec pistol ammo should not be used in other pistols - 25% hotter than other 7.62X25 ammo -

Background
The 7.62x25mm Tokarev cartridge is a bottle-necked pistol cartridge designed in the Soviet Union and widely used in the USSR and Soviet satellite states. It is effectively a more powerful Soviet version of the 7.63x25 Mauser cartridge.

The two are physically very similar and many weapons can chamber both. However, the significantly higher power of the 7.62x25mm Tokarev will likely lead to weapon damage and user injury. The Czech version is loaded to 25% higher pressure yet, leading to significantly higher velocity and energy but also to greater danger if used in weapons not designed for it! The Czech ammunition can safely be used in your sturdy CZ-52 but it must not be used in weapons not specifically designed for it

The Starline Brass site has this warning for reloaders:
This case [the 7.62x25mm Tokarev] is very similar, except for the difference in length, to the .30 Mauser. Due to higher operating pressures, if the .30 Mauser cases are fired with hotter 7.62x25 loads in the CZ-52, it will tear the neck off some cases. 30 Mauser O.A.L. is .980" to .985" while 7.62x25 O.A.L. is .958" to .962".

I'd never shoot Tok ammo in my Mauser. My reloads are a bit on the low side. I load it up until it functions reliably. No reason to risk a >120yr old pistol.

Be careful of load data. The Lyman 44th edition shows .30 Mauser data as I use it. Their 48th edition shows the Tok and Mauser combined, mentioning that some use them interchangeably. Their load data is obviously Tok level and their test gun is a Cz52. Please ignore that unless you have a 'disposable' Chinese broomhandle.

There is still some .30 (or 7.63) Mauser ammo available.

He doesn't have Czech ammo. He has Serbian (used to be Yugo) 7.62x25 Tokerev ammo.

Back in the early 90s when the Chinese were importing all those Broomhandle pistols for dirt cheap, it was common practice to buy the 7.62x25 Tokarov ammo to disassemble and then re-assemble with a more appropriate powder charge for feeding the Broomhandles. It was easy to do, too. You didn't even need the loading die set to do it. You only needed a Lee Factory Crimp die, and many fellas got away with using one for .32H&R, since the bottleneck cartridge headspaced on the shoulder rather than the case mouth. As I recall, the practice was to save the powder from the cartridge and replace it with only 90% of the original.

The PPU chronographs 1450 fps from my 1953 TT pistol vs. 1600 for S-B.

Still too hot for an M96.

Commercial .30 Mauser is 1300 fps @ 29,000 cup.

[K43]

Exactly.

I have had commercial PPU (NNY) 7.63 Mauser and PPU 7.62 Tok. You have to read the headstamp to tell them apart.
