The first version of this cartridge, 8 × 57 I ("I" - "Infanterie", translated from German - "infantry"), was developed by the Prussian arms test commission and adopted by Germany in 1888 along with a rifle Gewehr 1888. The cartridge 8 × 57 I had a rounded bullet, it is also known as M / 88 .
Later, an 8 × 57 IS cartridge was created ("S" - "Spitz", translated from German - "pointed", that is, with a pointed bullet). The cartridge 8 × 57 IS was the main cartridge of the German army during the First World War and World War II . The most widespread in the German army received a cartridge with a heavy pointed bullet sS (schweres Spitzgeschoss) weighing 12.8 grams. Intended for firing from easel, machine guns, rifles and carbines, which were in service with the Wehrmacht . For firing, including anti-aircraft, from machine guns MG 34 and MG 42 , a cartridge with an armor-piercing bullet SmK (Spitzgeschoss mit (Stahl) Kern) was created. A cartridge with a bursting bullet (B - beobachtung), used as a sighting cartridge, was also created [1] . It was banned for use on the Western Front, but was widely used on the Eastern.
There are also options for an 8 × 57 cartridge with a sleeve with a protruding rim : 8 × 57 IR and 8 × 57 IRS . The cartridges 8 × 57 IR and 8 × 57 IRS are used mainly in hunting unions .
Based on the 7.92 × 57 cartridge, the 9.3 × 57 Mauser cartridge was later created.
