The 6mm Norma BR cartridge introduced by Norma in 1996. It is based on the 6mm BR Remington cartridge, although where Remington's cartridge was intended for bullets of about 70 grains, Norma standardized their set of chambering specifications for a very low drag (VLD) bullet of over 100 grains, thus realizing the long-range capabilities of the cartridge. This resulted in a much longer neck on the Norma cartridge.[1]
