The 7.62x25mm is a type of ammunition originally developed in the early 20th century for the Tokarev pistol. It features a bottlenecked design, which allows for higher velocity and flatter trajectory, making it effective for both military and civilian use. This cartridge is known for its relatively low recoil and high penetration capabilities. Primarily used by the Soviet Union and various Eastern Bloc countries, the 7.62x25mm has been employed in several firearms, including submachine guns like the PPSh-41. Its distinctive performance characteristics have made it a popular choice among collectors and enthusiasts of historical firearms.
