The 7 x 57mm caliber is a rifle caliber introduced by Mauser in 1892. In the USA it is also traded under the designation 7mm Mauser, another designation, although rare, is .275 Rigby. The high precision and especially the low recoil make it a popular hunting cartridge, which has lost some of its popularity since the introduction of the 7 x 64 mm by Brenneke. In terms of shooting behavior, the 7 x 57 caliber can be compared to the .308 Winchester cartridge.
