6.5×53mmR

The 6.5×53mmR or .256 Mannlicher is a late 19th-century rimmed centerfire military rifle cartridge similar to other early smokeless powder designs. It was the first of a series of 6.5 mm Mannlicher cartridges and became the standard Romanian service rifle cartridge from 1893 to 1938, and the standard Netherlands service rifle cartridge from 1895 to 1945.
