The 6.5×57mm Mauser (designated as the 6,5 × 57 by the C.I.P.) is a smokeless powder rimless bottlenecked centerfire rifle cartridge developed by Paul Mauser and introduced in 1893–94.
The 6.5×57mm Mauser was designed and introduced by Mauser in either 1893 or 1894 for use as a sporting cartridge; the cartridge was created by necking down the 7×57mm Mauser.
The 6.5×57mmR Mauser (designated as the 6,5 × 57 R by the C.I.P.) is a rimmed variant of the 6.5×57mm Mauser.
The 6.5×57mm Mauser never saw military service with any power, but it influenced the design of many 6.5mm military cartridges such as the 6.5×58mm Vergueiro.
Several wildcat cartridges have subsequently been created from the 7×57mm Mauser with almost the same caliber bullets, such as the .257 Roberts, but are not interchangeable.
The rimmed variant was designed for break-open rifles and is almost identical to the rimless option except for the rim and a significant lower Pmax piezo pressure.
