8 X 57 JS (8mm Mauser), Full Metal Jacket (FMJ), 0.323-inch bullet diameter, Rimless Cartridge, 196 GR, 2589 fps, 20 Rd/bx
A full-jacketed bullet consisting of a lead core provided with a metallic jacket. Due to its rigid design, the bullet makes a smooth bullet hole in the tissue, because it does not get deformed when hitting the target. It is used for trophy game hunting and competition shooting.
Germany adopted what is now commonly known as the 8mm Mauser in 1888. Soon the military of a number of other countries, including Czechoslovakia, Poland and China were using it, too. In 1905, Germany increased working pressure of this cartridge and switched from a 226-grain, 0.318-inch, round-nose bullet (2095-fps) to a 154-grain, 0.323-inch, spitzer bullet (2880-fps – phenomenal velocity for that era). The reason behind the increase in bullet diameter was that the grooves of all existing military 8x57 J barrels were deepened, to extend useful barrel life; all new barrels were specified with the deeper grooves; bore diameter was unaltered. The 8x57 JS is a flexible and powerful cartridge and duplicates 30-06 performance. Few bolt-action rifles have recently been chambered for the 8x57 JS, which is too bad. This is a fine old chambering that, in competent hands, is suitable for hunting most species, worldwide.
The United States standardizing body for sporting cartridges Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) designates the 8x57mm JS cartridge as the 8mm Mauser.
