What weapon are 7.62x25 strippers designed to feed?

Got a crate of Czech surplus, it came on 8 rd stripper clips, 5 to a box. I'm guessing the clips charge some sort of SMG. Which one(s)? I have to peel the clips to load my TT33.

I've called them CZ26s but there are some alternate designations.
Only had access to one for a few months several years ago, but it was quite efficient.

There's a little recess on the right side of the front hand hold where you can place the charger/clip to help load the magazine.

I thought the 8 round stripper clips were for use in the CZ 52 pistol?

The ammo is, the pistol has no charger guide on the slide like say, Mauser broomhandle.

If it's on clips, it was intended for the submachine gun. The CZ52 pistol is about the only handgun in which this ammo is safe to shoot. MUY HOT!

It works fine in my TT33, but its DIRTY. The little buggers also shred and shed their jackets at first contact with anything, while the core keeps going. Would not want to be hit with one, they'd never find all the grubby little pieces of the bullet.

The Czech is a little hotter than most other flavors of 7.62 Tokarev, but not markedly so. It is perfectly safe in any pistol chambered for 7.62x25 Tokarev. If you do a little internet research, you will find that the TT is actually stronger than the CZ52, and has survived much higher pressures. The Czechs loaded the rounds on strippers for the SMG shown above, but the rounds, per the box labels, were intended for both pistols and SMGs.

I chronographed some of the Czech stuff some years back and it ran near on 1650-1700 fps. I may have gotten some odd ammo, as I can't read the labels. Usually it seems 7.62x25 or 30 Mauser runs 1250-1400 fps, but I'll surely defer to jonnyc. I've heard tales of all sorts on this family of ammo, and have run only the most limited tests.

The most telling thing is that I've never seen any sort of wrecked 30 Mauser or 7,62x25 handgun, so... I just don't want to be the first to do it!

"Generally", .30 Mauser is slower than most 7.62 Tokarev, but not in all cases. I've read tests where some wartime 7.63 Mauser ammo was hotter than some lighter Tokarev fodder. I think most Tokarev velocities I can recall were in the 1450-1550 range.

A late edition of Small Arms of the World calls the submachinegun a Model 24. It also notes that the ammo runs at 1660-1800 fps, but the increase could be due to the longer barrel. It does mention the rounds were loaded to higher than standard velocities, but their sources could have been in error.

Having only handled the one submachine gun, and not having a CZ52 currently, I don't have much way to do a heads up comparison. The only thing roughly in that caliber I have to shoot is a Mauser-and it only eats nice, new ammo!
