), introduced in 1900, is closely related to the 9×57mm Mauser, even though some dimensions of the cartridge case are slightly different.

The 9.3×57mm Norma factory load with a 232 grains (15.0 g) bullet has a muzzle velocity of 2,362 feet per second (720 m/s) for 2,875 foot-pounds force (3,898 J) of energy, which makes it 10-20% more powerful than the 9×57mm.

The 9.3 mm bullets (.366" diameter) loaded in this cartridge come in 232 and 286 grain weights.

[2] Cartridges of the World [3] lists reloading information for both the 232 and 286gr bullets using IMR3031 powder as well as showing a Norma factory load.

The loading information has not been updated to reflect newer powders than IMR 3031.
