The 7.62×25  cartridge is a Russian  rimless bottlenecked pistol cartridge widely used in former Soviet states and in China, among other countries. The cartridge has since been replaced in most capacities by the 9×18mm Makarov in Russian service.[6]

Various Tokarev cartridges achieve muzzle velocities around the range of 1,300 to 1,800 fps. A common velocity is around 442 metres per second (1,450 ft/s) with about 544 joules (401 ft⋅lbf) of energy. Given the wide disparity in ammunition manufactured in many different nations, ammunition is encountered that yields higher and lower velocities. Some newly manufactured ammunition intended for commercial use has a velocity of approximately 1,560 feet per second (480 m/s).

Wolf Gold FMJ tops out at 1,720 feet per second (520 m/s) with 745 joules (549 ft⋅lbf) of energy, as does PPU ammunition. Some of this ammunition, such as the Wolf Gold and Sellier & Bellot, use boxer primed brass cases that are reloadable.

In 1929, the Soviet Artillery Committee made a proposal to develop a domestic pistol chambered for the Mauser cartridge. After considerable research and development, it was decided that the “Model 1930 7.62 mm pistol cartridge,” essentially the Mauser round with minor modifications, was to become the standard caliber for Soviet pistols and submachine guns. Early versions of the Vasily Degtyaryov-designed PPD-40 submachine gun were marked for Mauser cartridge caliber 7.62 mm.

Although dimensionally similar to the Mauser cartridge (so much so that both cartridges will chamber, load, and fire in any of these firearms), the Soviets increased the power of the Tokarev cartridge powder charge significantly. As such, while the lower-power Mauser rounds can be safely used in any of these firearms, the Tokarev cartridge is not safe for use in firearms which were not designed for the added pressure.
