The cartridge is also known as the 6mm Bench Rest or simply 6 BR, and has also developed a following among varmint hunters because of its efficiency.

The new cartridges’ accuracy and efficiency was noticed by the bench rest shooting community.

[14] However the chamber of the Norma version provided a longer throat making allowances for the seating of very low drag (VLD) bullets.

[12] It was designed from the beginning to optimize accuracy, barrel life, and case capacity in a 6 mm cartridge for 300–600 metres (328–656 yd) target shooting.

As such it couples a sensible case volume (2.45 ml) to bore area (29.52 mm2/0.2952 cm2) ratio with ample space for loading relatively long slender projectiles that can provide good aerodynamic efficiency and external ballistic performance for the projectile diameter.
