The Russian designed 7.62x25 Tokarev is a higher pressure version of the slightly older Mauser version. The Russians copied the Mauser's exact measurements essentially, and created a higher pressure variant for use in many of their submachine guns and sidearms at the time. The cartridge still sees use today in many nations because there is so much surplus in Eastern Europe.
This round is still manufacture new, but performance can vary. Feet per second can go from 1300 to just under 2000, depending on who assembled the cartridges. Wolf, PPU, and Sellier & Bellot are among the group of manufacturers that still sell newly created 7.62x25 Tokarev, and these consumer grade cartridges average around 1450 FPS muzzle velocity.
