The 5.6×50mm Magnum (designated as the 5,6 × 50 Mag. by the C.I.P.[2]) is a centerfire, rimless, bottlenecked rifle cartridge that was developed in 1970 by Günter Frères of the Deutsche Waffen und Munitionsfabriken (DWM).

Parent case

[edit]

In 1968 Günter Frères developed the parent case, the rimmed 5.6×50mmR Magnum (designated 5,6 x 50 R Mag. by the C.I.P. According to the official C.I.P ruling, the rimless 5.6×50mm Magnum can handle up to 380.00 MPa (55,114 psi) Pmax piezo pressure, which is 40.00 MPa (5,802 psi) more than the rimmed parent case developed four years prior.[3]

Uses

[edit]

The 5.6×50mm Magnum and 5.6×50mmR Magnum cartridges were developed in Germany as legal hunting cartridges for small game, fox, chamois and roe deer at ranges up to and over 200 m (219 yd).[4] In North America it is considered a varmint hunting cartridge.[1]

[edit]

This cartridge occupies a useful performance niche approximately halfway between the .222 Remington and the 5.6×57mm, similar to the slightly less powerful .222 Remington Magnum and the .223 Remington.[citation needed]
