What weapon are 7.62x25 strippers designed to feed?

If you read the Czech 7.62x25 box labels, they always say the ammo is for pistols or pistols and SMGs. I have examples of all known Czech Tokarev boxes, and none say For SMG Only.

OK, then!

Have you shot any over a chronograph?

Just got a PPS43 pistol, but it has a bit longer barrel than the various pistols. Maybe a CZ52 (or a bring-back TT33!) will show up some time soon, and then a test of various ammo types could be done. I think there's a 1000 or 1500 rounds of Czech stuff handy- Don't remember what else...

Here's a link to a site that also lists the Czech ammo as being loaded hotter:

7.62x25mm Tokarev Ammunition for the CZ-52

In actual fact, I was looking for the cheap milsurp ammo that was available recently- but it seems to be gone! Typical.

back in the day, I carried one of those , chambered in 9mm. nice little SMG

Same SMG, but different model number(s). I think the 7,62 versions came along to standardize calibers with the rest of the Warsaw Pact nations.

Perhaps the Czech uploaded their ammo as a minor protest against a fairly forced inclusion into the Communist sphere.

Found yet another confirmation today in my 1977 Jane's Infantry Weapons, which stated that their loads (including the rounds for the Vz52 pistol) were 20% hotter than standard 7,62x25. This is the first reference that specifically included pistols that I've found, which would explain why there's no special marking on the Czech boxes of ammo.

And here's a thing which has bothered me.

I have a 1911 Steyr pistol in the original 9mm Steyr calibre. The Czech chargers work on this pistol; I first became aware of this when a batch of Czech 9x19 was sold here, at a time when Steyr chargers were utterly nonexistant.

Does anybody know: were any 1911/12 Steyr pistols ever converted to handle the 7.62x25?
.

None of which I'm aware. 9x19, yes. But have never seen nor read about a 7.62x25 conversion.

As I'm Steyr Hahn-less at the moment, it's pure conjecture, but I can't think of any particular it wouldn't work, unless the body taper is excessive and the rounds bind up in the grip when fully loaded.
