6mm BR
The 6 mm BR Remington is a cartridge for benchrest shooting (BR ). It was developed by Remington in 1981 as competition to the 6 mm PPC. The sleeve of this cartridge is shorter and thicker than the sleeve 6 mm PPC. The trend to similar sleeve forms can also be seen in the cartridge .300 WSM.
