9×57mm Mauser

The 9×57mm Mauser is a cartridge based on the 7.92×57mm Mauser. It uses the identical 57 mm-long cartridge case, with the same shoulder angle, but necked up to accept a 9 mm-diameter bullet. Ballistically - but not dimensionally - it is indistinguishable from the 9×56mm Mannlicher–Schoenauer. It is currently regarded as a semi-obsolete calibre, although hand-loading keeps it alive.
