I believe the Tokarev round is of the 9mm Para parentage for its case, and necked down.
Thanks for correction.Sorry, but this is incorrect. The 7.62x25mm Tokarev round is not derived in any way from the 9mm Parabellum.
The Tokarev round is a Soviet version of German 7.63 Mauser round. It is almost exactly dimensionally the same and the handgun ammo is loaded to similar velocity and pressure. Some Soviet SMG ammo is hotter.
It will NOT fit in a .32acp barrel, the round is significantly longer AND the case body is "fatter". It will not chamber or fit in the .32acp magazine. The ONLY thing the two have in common is the .30 bore of the barrel.
The Broomhandle Mauser and its cartridge (.30 Mauser) were popular in Russia before the First World War, and continued to be popular after the Communists took over, In the early 1930s, the Soviets began loading their own version of the 7.63 Mauser for their new pistol design (the T-33 Tokarev) and called it the 7.62x25mm.
It was not based on either of the Luger rounds, though the rim size is almost the same, the case is considerably longer.
Sorry, but this does not exist.
I know 7.62x25 is for Soviet arms only. Never heard of any more specifics than that. Proving nonexistence is indeed high bar. Only take one single piece evidence of existence to knock it down. Haven't seen one yet.
-TL
I happen to have the largest collection of 7.62x25 ammo in the world (not a brag, just fact), including boxes, packets, and documentation. In over 25 years of this pursuit I haven't seen a single shred of info on any Tokarev cartridges loaded exclusively for either pistols or SMGs.
I have yet to see a pistol magazine that will take the 7.62x25 ammo directly from the stripper clips.
The information I've seen, over the years (and all in English) is all over the place about which round is "hotter". I've got some data that says the Mauser is faster (but only by less than 50fps) others say the Tokarev is hotter and don't use it in Broomhandle Mausers....
When you don't have the pressure information, all you have is the given velocity, the actual pressure specs are irrelevant.
And also, without having the pressure rating of the ammo you are using, you cant know if it is loaded to the industry max, or something else.
I've got some data, published in the 60s, stating the Mauser is an 86gr bullet and the Tokarev is an 87gr. Says the Mauser does 1410fps and the Tokarev does 1390fps.
Pressure is not mentioned, nor is barrel length, only bullet, velocity and ME
Sure, its far from complete, but when you only have what they give you for information, that's what you go on. or don't go, at all.
I have also seen other data (and also less than completely documenting everything) which shows the reverse, with the Tokarev being a little faster than the Mauser.
TO me, this makes the two essentially identical in performance, as literally, anything less than over 100fps difference in speed can be attributed to the individual firearms being tested.
Tokarev #1234 might be 30fps slower than Mauser #1245 and Tokarev # 4567 might be 50fps faster than Mauser# 1245 and slower than Mauser#5567 or Tokarev #8888.
Individual guns can, and do play more of a role in velocity than the ammo specs alone indicate.
