7.62x25 in an Rifle made for 7.62x39?

[mdmaroon]

I'm not saying this would be a good idea. I'm talking disaster survival scenario here...

Could you fire 7.62x25mm Tokarev ammo from a rifle made for 7.62x39mm, like an SKS?

I don't mean "Would it cycle reliably?" I mean "Could you manually load one round and fire it without blowing yourself up?"

I've never seen a 7.62x25 round, except in photos, so I have no idea if this is even within the realm of possibility. Maybe it would be like putting a square peg in a round hole. Couldn't find much with Google...

great question l would likely know too.

you can buy atapters that hold a .32 acp or a 7.62x25 in a steel case shaped like a 7.62x.39 or x54r or .303 brit

If you mean shooting 7.62x25 in a 7.62x39 chamber then no probly not unless you could get the round to stay on the bolt with lining the primer and the firing pin lined up. It shouldn't be to dangerous, try it. lol There ar chamber liner to use 7.62x25 and .32acp in a mosin but I read they are no good past 25 feet since 7.62x25 uses .310 bullets and the twist rate is way off.

But wouldn't it be easier to just buy a case or 2, or even a spam can of surplus just in case? Or buy a .22 if you want a quiet small game gun?

 

[mlehtovaara]

Seriously?

The only similarity is the bullet diameter. The cartridges are completely different.

A chamber adapter would be the only way.

Google or wikipedia could have answered your question pretty quickly and easily.

Thanks for the responses. So basically it can be done, not that I'm going to try.

In survival situation you can use whatever fits in the chamber, even 5.56 nato. It wouldn't be accurate shots, it might not fire at all, empty cartidges might not extract well, componetns might have excess wear but it won't blow up as long as bolt carrier is fully closed. Shorter cartridge has it's implication - if you manage get it full way in chamber firing pin won't hit it, but if it held by extractor and firing pin strokes then bullet might not be fully aligned with the barrel and damage chamber. I said I won't blow up, but it this case I'm not sure what happens.
So I wouldn't risk unless I really had no other choice.

The x25 case is smaller in diameter and shorter than the x39 case. If it were glued to the boltface so that the firing pin could strike the primer, the case would rupture.
Even in a doomsday scenario, it would be a foolish thing to attempt.

 

[mdmaroon]

So I would need some doomsday epoxy putty which I would put around the cartridge, which would be covered in doomsday vaseline, and shove that in the chamber until the epoxy hardens.

Oh, gotta go. I have a parrot preening my eyebrows...

if it came to the point where your life depended on it.....you'd probably be better served using your rifle as a club..oh and there's that pointy thing

If you look at the soviet ergonomics of most of their weapons, you will see that club was thought of as a secondary use when out of ammo!!

You can remove the trigger group, remove the stock, and extend the bayonet.

Then you can use the trigger like brass-knuckles, the stock as a club, and the rifle as a spear.

Or you can attach a fishing reel to the side of the stock, run the fishing line down the barrel, and you've got yourself a fishing rifle.

SKS is miracle!

 

[enefgee]

That would be a fun kaboom.

If you don't have a chamber adapter, the best answer is no...
If you think you will run out of 7.62x39 then buy some more.
Talking disaster/survival situation, you'd be better of just filling your pockets with rocks to throw than risking injury and damage to your rifle for basically no chance of any positive outcome.

I'm sure with enough duct tape it's possible.

I pulled some bullets from 7.62x25. All 3 types used 0.308" bullets. This was Milsurp.

I have adapters to all their use in 7.62x54 and 303 Brit.

While 7.62x25 in a x39 chamber is really pushing it, I think a lot of folks here are forgetting the concept of fire forming which is a widely practiced and safe exercise to obtain cases in an otherwise unobtainable caliber. Just because the cartridge doesn't match the chamber does not mean you're going to blow the gun up.

Like I said, the calibers under discussion wouldn't be compatible dimensionally but the concept works if you know what you're doing.

 

[boots-]

but with fire forming you dont use a bullet and you dont expect it to shoot, you use oatmeal or whatever floats your boat, the pressure differance is large

 

[AK]

You can absolutely fire form with live projectiles. Plenty of examples in YouTube and Google. Generally shoulder forming but that's academic with the cartridges the OP asked about.

Chamber insert is still the way to go when viable. I was simply pointing out that voids between your case and the chamber walls are not always catastrophic (and certainly not with the pressure differences between x25 vs. x39 - 40,000 vs 51,000 psi).
