The 7.63 mm Mannlicher or 7.65 mm Mannlicher is a centerfire rimless pistol cartridge developed for the Steyr Mannlicher M1901 pistol. This military pistol was rejected by the Austrian Ministry of War, but was often carried as a private weapon by officers. The United Kingdom began manufacturing ammunition when the Mannlicher pistol became popular in South America. Germany began manufacturing ammunition after World War I, but identified the ammunition as 7.65 Mannlicher to differentiate it from the 7.63×25mm Mauser cartridge. This cartridge headspaces on the mouth of the case.[1]
