The 8x57 JS, also referred to as the 7.92x57mm Mauser or 8mm Mauser, was introduced into service for the German Empire in 1905. This cartridge was used by Germany in World War I, and by Germany, Poland, and Great Britain in World War II. Just a few years later, Israel used surplus 8x57 JS cartridges and Mauser rifles, as well as other surplus rifles, in their War for Independence. Egypt also manufactured the Hakim rifle chambered for the 8x57 JS and issued them to their troops. The use of the cartridge more recently has been restricted in scope, but has seen action in the Yugoslav wars during the 1990’s, and the 2011 Libyan Civil War.

Today, the 8x57 JS is most commonly used for hunting, being able to harvest any game animal on earth. The most abundant rifles chambered for the 8mm Mauser are the K98 Mauser rifles and variants, and several other rifles made in Europe. Remington in 2004 produced a limited edition Model 700 chambered for 8x57 JS, but has since stopped production. Ammo is manufactured mainly by European companies including Sellier and Bellot and Privi Partizan.

The impressive ballistics of the 8x57 JS are comparable to the .30-06. Bullets weigh between 152.8 grains and 197.5 grains, muzzle velocities approach 2,900 feet per second, and muzzle energy easily exceeds 2,700 foot pounds. An interesting fact, the 197.5 grain Boat Tail Hollow Point bullet which the Germans used in WW II traveled faster than the speed of sound even well beyond 1,000 meters. The most common projectiles for the 8x57 today are Full Metal Jacket bullets and Soft Point bullets.

The 8x57 JS remains an excellent cartridge for hunting that is likely to stay popular among European hunters. The cartridge was never wildly popular in the United States, but the 8x57 JS has earned its place among the group of European cartridges collected by shooters across the country.
