The cartridge was created by reducing the neck of the 6.5×57mm Mauser by 2 mm. The .256 Gibbs Magnum is very similar to, but not interchangeable with, the 6.5×55mm Swedish cartridge. One famous user of the .256 Gibbs Magnum was Denis D. Lyell who used a rifle in this calibre for hunting in Africa. See also List of rifle cartridges References Frank C.
