History
Developed by Mauser in 1896 for the C96 pistol. The bottlenecked case and high velocity (over 1,400 fps) made it one of the most powerful pistol cartridges of its era. Used across WWI and WWII by multiple nations. Winston Churchill carried a C96 in the Mahdist War. The Soviet Union copied the cartridge dimensions nearly exactly when developing the 7.62x25mm Tokarev in the 1930s. Original 7.63mm Mauser ammunition is collector-grade; modern production 7.62x25mm Tokarev is generally safe to fire in C96 pistols.
