762x25

7.62x25mm, also written as 7.62×25mm Tokarev, is a pistol and submachine gun cartridge developed in the Soviet Union in the 1930s by Fedor Tokarev for the TT pistol. It is a bottleneck, rimless cartridge with a case length of 25 mm and a bullet diameter of about 7.62 mm. Most loads use a cylindrical jacketed bullet of roughly 85 grains (5.5 g). Muzzle velocities typically range from about 1,450 to 1,800 feet per second (440 to 550 m/s), depending on the load and firearm.

Historically, the cartridge entered service in the mid-1930s and saw extensive use by Soviet forces during World War II and the early Cold War. It was chambered in the TT pistol and was widely used in submachine guns such as the PPSh-41, PPS-43, and PPD-40, all designed to exploit its high velocity in short-barreled weapons.

In the postwar period, many armed forces shifted to 9 mm rounds, but 7.62x25 remained in limited production for decades to support existing firearms. Today, surplus ammunition and pistols are available to collectors and in some markets, and a narrow range of manufacturers continue producing modern loads for historical firearms. The cartridge remains a notable example of early 20th-century Soviet small arms design and usage.
