The 7 × 57 mm is a rifle cartridge. The 7 stands for the caliber and 57 for the length of the case (in mm).
The military cartridge 7 × 57 mm was constructed by Mauser in 1892 based on the case M / 88 . Due to its very good precision and low recoil for the time, it was quickly introduced by Spain and Central and South American countries as a military cartridge in conjunction with the Mauser rifle.
In 1893 the 7 × 57 mm was also introduced as a hunting cartridge . Again, the precision and especially the low recoil helped the 7 × 57 to spread quickly and widely. Later, however, the faster 7 × 64 mm from Wilhelm Brenneke overtook it . Nevertheless, the 7 × 57 mm is still widely used today as a hunting cartridge. In the USA it is known as the 7 mm Mauser.
A rim cartridge with the designation 7 × 57 R is also available for use in drop barrel weapons .
