ammo interchangeability

Here’s one that’s bound to create some controversy.

Based on what I read, some say 7.62 Mauser and 7.62x25 are interchangeable.

No personal experience, there are those who say it’s okay, and those who say the sky will fall.
 
.460 S&W can also shoot .454 Casull, .45 Colt, and .45 Schofield.
Can certainly doesn't mean can safely!
Our .454Casull is not designed to shoot .45Colt even though the Taurus Raging Bull and some others are used that way.
Freedom Arms 454"Casull has a .45Colt cylinder and from stories I have read there was a blown cylinder that I'd said to have been caused by buildup of fouling from the shorter round.
I/we have the .45Colt cylinder serial No to the Model 83

In the early 80s (life before the information age), one of several guns I inherited from my grandfather was a 1914 Mauser pocket pistol. This was a war souvenir and had some army paperwork riding with it. The paperwork called it a 'Luger'. The box it was in had a whole assortment of loose ammo, all of it completely wrong, but there were actually several spent 32 s&w cases too.

The problem of what fits what is clearly not a contemporary one.

Well, Lyman's 50th edition reloading manual calls them interchangeable. There is a very tiny difference on case length which is inconsequential. Either round will chamber in either gun. Which brings us to....
Well, only if you want to destroy your $$$$ Broomhandle.
I've been shooting Tok ammo in my broomie for years, and a few thousand rounds later it is just fine. A few points to consider:

The Russians never loaded the 7.62X25 any hotter than the Germans loaded the 7.63 Mauser round. There was simply no reason to do so. And the Germans loaded it pretty hot!!1 85 gr @ 1575 according to Small Arms of the World.

There is not now and never was any Subgun ammo in 7.62X25. Ask JohnnyC. He is a cartridge collector that specializes in 7.62X25 and 7,63 Mauser ammo.

The myth has been circulating for years that the Soviet ammo was loaded to higher pressures than the Mauser. Nyet! Nein! Nada! simply not true. But even if it was...

The C-96 is a pretty strong gun. It was chambered in 9X25 Mauser, which was loaded to higher pressures ( 37,500 PSI ) than a .38 Super ( 36,500 PSI ) and fired a 128 gr bullet @ 1360. Here's a scary thought. A 9X19 will chamber in a 7.63 chamber AND FIRE!!! A member on this forum did it! He stopped after three or four shots because the gun seemed to be kicking harder than usual! He found that the gun was unharmed. He did recover one of the bullets. It had been squeezed from .355" down to .308" and was almost an inch long. I can't think of a worse torture test than this.

Have you ever seen a box of 7.62X25 ammo with a warning not to shoot it in a C-96? Neither have I.

Having stated all of the above, I will now state this; Before firing ANY broomhandle, first make sure the gun is in good shape. Replace every spring on the gun. The hammer spring is critical. It provides the initial resistance to movement by the barrel extension and bolt. If it is weak, the gun will beat itself to death in short order. The bolt spring is almost as important. If both springs are weak, the pictures below show what can happen. This gun was firing the correct 7.63 Mauser ammo. Notice that the bolt stop is intact and did NOT fly out of the gun. This is another myth circulating about C-96s. Bolt stops do not shear because of firing too many hot loads in the gun, and fly back in the shooters face. They can't fly anywhere because the firing pin passes through them and secures them in place. They are made of harder steel than the barrel extension, And the pictures show what can happen when hardened steel crashes against softer steel

That sounds very spicy.
Small Arms of the World also shows the 7.62 Tokarev at only 1378 fps which gives me leave to doubt their numbers for the Mauser. One of Phil Sharpe's loads for the Broom gives that velocity.
The 1939 Stoegers shows different brands of .30 Mauser ammo from 1380 to 1400 fps.

That Stoegers offers a Mauser 712 "20 shot" detachable magazine Broomhandle, with footnote that it is not selective fire like the home market Schnellfeuer.

You can safely shoot 7.63x25mm Mauser in a gun chambered for 7.62x25mm Tokarev. Can't do it the other way around.

Same goes for .38 ACP and .38 Super. You can shoot .38 ACP to your heart's content in a gun chambered for .38 Super.

Totally wrong!

If it was unsafe to shoot Tok ammo in a C-96 there would be warnings on the box saying so.

Read my last post and let it sink in. A C-96 in good condition can safely shoot any 7.62X25 factory loaded round, including ComBlock ammo.

You are quite correct about the Super and the .38 Auto.

Cartridges Of the World lists the Mauser round @ 1410 FPS and the Tok round @ 1390 FPS. I don't think either figure is correct today.

A number of manufacturers don't really put warnings on their box. I don't see my boxes of .44 Russian saying, "don't shoot in .44-40 guns."

That's because most manufactures load their ammo with pressures safe in any gun chambered for that round. Most simply state that the ammo should only be used in guns in good condition and marked for that particular caliber.

You might have a bit of trouble firing 44 Russian ammo in a 44-40. The Russian ammo is shorter, the case is smaller in diameter and the bullet slightly larger and heavier.

.327 Federal Magnum will shoot .32 H&R Magnum, .32 S&W Long, and .32 S&W (Short).
And in my Bond Arms .327 Federal Magnum barrel I shot a couple dozen .32 ACP with no problems other than they slipped past the ejector and I needed to poke some of the cases out with a stick from the muzzle.
 
Privi shows higher velocity for Tokarev than Mauser, both way higher than above.
Winchester white box 7.62X25 comes in at around 1650 FPS with the 85 grain bullet. Not necessarily higher pressures, just advances in modern propellants. Ammo companies aren't going to increase pressures on a cartridge that has been around for almost a century without a warning on the box. Too many old, worn out Tokarevs lying around .

You didn't have any problems because the .327 is loaded to nearly twice the pressures of a .32 ACP. Shooting the latter in an old, black powder revolver is an invitation for disaster.

I know some Czech 7.62 Tok was hot stuff. Hotter than typical 7.63 Mauser.
 
For all of you who think Tokarev ammo is unsafe in a C-96...

It is loaded to less pressure than than the 9X25 Mauser was. (37,500 PSI. ) A C-96 in good condition will have no trouble handling Tokarev ammo.

No, you don't. That is another myth that has been repeated for decades. The former Soviet Union did not allow one subjected nation to load pistol ammo that was dangerous to shoot in the pistols of the other member nations.. And, as we know today, the CZ-52s were a weak, flawed design that had numerous trouble areas and were riddled with breakages and failures. Firing pins that broke with even a limited amount of dry firing. Rollers that deformed and froze up the gun. Or they galled because of faulty heat treatment with the same result. From a military standpoint, where longevity and durability were paramount...the CZ-52 was one to histories worst military handguns.

This is a small collection of the wrong cartridge chambered and fired I found today in the Range Clubhouse.
