7.92x57mm Mauser

Germany’s rimless 7.92x57mm Mauser cartridge was invented in 1888, and its rimless design was incorporated into many subsequent military rifle cartridges. Also known as the “8×57 Mauser,” it propelled a 225-grain, .318-caliber, round-nosed full metal jacket (FMJ) bullet at almost 2,100 feet per second (fps). In 1905, the round was modernized by adding a long-range, 154-grain, .323-caliber, spitzer bullet at 2,890 fps. The round was changed after WWI to feature a 198-grain spitzer at 2,575 fps.
