7.62x25mm

The 7.62x25mm Tokarev cartridge was originally designed by Fedor Tokarev for his TT-30 and TT-33 semi-automatic Russian military pistols. When fired from TT-series pistols, it propels an 87-grain, 7.62mm bullet at 1,390 fps. The PPSh41 submachine gun was also chambered in 7.62x25mm, and it played a major role in the defeat of the German Army during WWII. While obsolete, Tokarev pistols and ammo are most likely still in military service around the world.
