The 5.6x50mm Magnum cartridge was developed in Germany for use as a legal hunting round alongside the 5.6x50mmR. The two cartridges are dimensionally and ballistically identical in all respects, except that the Magnum cartridge is not rimmed.
Typically firing a 50-grain (3.2 g) bullet at c.3,400 ft/s, this cartridge occupies a useful performance niche approximately halfway between the .222 Remington - 3,100 ft/s (940 m/s) - and the 5.6x57mm - 3,900 ft/s (1,200 m/s), similar to the .222 Remington Magnum. In Germany the cartridge was used with appropriate bullets to hunt deer, in America, it was primarily a varmint hunting cartridge.[1]
