7×57 Spanish Mauser

7×57 Spanish Mauser

This round was developed in Germany by Mauser factory for their improved rifle in 1892. It was adopted by Spanish army in 1893 along with Mauser bolt-action military rifle, and since then it was also adopted by several other South American countries as well. As a military round, this cartridge gradually became obsolete after WW2, but it is still chambered in several models of hunting rifles and thus it is still manufactured for civilian consumption (mostly loaded with hunting-type rifles).
