.256 Mannlicher / 6.5x53R Reloading Data[6]

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-millimetre (0.26 in) Mannlicher cartridges[1] and became the standard Romanian service rifle cartridge from 1893 to 1938,[3] and the standard Dutch service rifle cartridge from 1895 to 1945.[2] Dutch ammunition with cartridge cases made of brass (pre-occupation) or steel (under German occupation) may be encountered on the American surplus market. In both instances, the primer pocket is Berdan-style, of an unusual type (Roth-patent), and features a central flash hole running through the center of the integral Berdan anvil. When examining fired cases from the inside with a flashlight, this design gives the false impression of a Boxer primed cartridge case.


For the handloader, Boxer-primed cartridge cases can be made by resizing and trimming .303" British brass.
