The 6mm Norma BR (Bench Rest) is designed specifically for precision shooting competitions, and is renowned for its exceptional accuracy. Developed from the 6mm BR Remington, it has a case length of 1.56 inches (39.62 mm) and uses small rifle primers. The cartridge typically fires a 6 mm (.243 inch) bullet, which provides an optimal balance between ballistic performance and manageable recoil.
Key attributes of the 6mm Norma BR include a relatively short, fat case that enhances powder burn efficiency and consistency, contributing to its excellent accuracy. It is a favored choice among benchrest shooters and is often used for target shooting at ranges up to 300 yards. While it is capable of being used for small game hunting, its primary application remains in competitive shooting arenas where precision is paramount.
