The 5.6x50mmR is a rifle cartridge developed in Germany in the 1970s by RWS (Rheinisch-Westfälische Sprengstoff-Fabriken). It is a rimmed version of the 5.6x50mm cartridge and is primarily designed for use in combination guns, such as break-action rifles and drillings, which are popular in Europe for hunting.
This cartridge is known for its flat trajectory and high velocity, making it suitable for hunting small to medium game, including roe deer, foxes, and similar-sized animals. The "R" in its designation stands for "Rimmed," which helps in distinguishing it from other similar cartridges and indicates its suitability for break-action firearms.
The 5.6x50mmR typically features a bullet diameter of 5.7mm (.224 inches) and a case length of 50mm. The typical bullet weights range from 50 to 60 grains, and the cartridge is known for being accurate at moderate ranges.
Its popularity is mainly confined to Europe, particularly in countries like Germany and Austria, where combination guns are more commonly used for hunting.
