Rifle cartridge From Wikipedia, the free encyclopedia
The 9.3×57mm was created by necking up the 7.92×57mm Mauser cartridge. The 9.3×57mm (bullet diameter .365 in.), 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 is still fairly popular among moose hunters in Scandinavia (among hunters in Sweden it is affectionately known as "potatiskastaren", the spud gun, because of the slow and heavy bullet). Factory loaded ammunition with 232 grains (15.0 g) and 285 grains (18.5 g) bullets is available from Norma of Sweden. 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.[1]

It is used for hunting wild boar and elk in Scandinavia. 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 loads listed in Cartridges of the World are valid, but dated. The loading information has not been updated to reflect newer powders than IMR 3031.
