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 5.6×50mmR Magnum

In 1968 Günter Frères of the Deutsche Waffen und Munitionsfabriken (DWM) had developed the parent case the rimmed 5.6×50mmR Magnum (designated as the 5,6 x 50 R Mag. by the C.I.P.[3]). According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the rimmed 5.6×50mmR Magnum can handle up to 340.00 MPa (49,313 psi) Pmax piezo pressure. That is 40.00 MPa (5,802 psi) less Pmax piezo pressure than the rimless 5.6×50mm Magnum.

Uses

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]

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.
