     Until the introduction of the 9x33mmR (.357 Magnum) round in 1935, this was the highest-velocity pistol round commercially available. A number of handguns and submachinegun were chambered for it, particularly the M1896 Mauser “Broomhandle” line of pistols which introduced it. The cartridge came directly from the earlier 7.65x25mm Borchardt which it is dimensionally similar to but it is loaded to a much higher chamber pressure for the stronger M1896 Mauser design. The 7.63x25mm Mauser round has been used widely around the world and a number of counties have their own line of the round, sometime under their own name.
