The 8x60mm S (the S means it is intended for 8.2 mm (.323 in) groove diameter bullets) is an uncommon rimless bottlenecked centerfire cartridge of German origin, dating back to the interbellum period between World War I and World War II. As is customary in European cartridges the 8 denotes the 8 mm bullet caliber and the 60 denotes the 60 mm (2.362 in) case length. The 8x60mm S can, due to its 83.6 mm (3.291 in) overall length, easily be chambered in standard sized Mauser 98 bolt action rifles.
