Brownells 75th Anniversary - A Shooting Heritage
Menu

The 6mm BRA (6BRA,  6 BRAI, or 6m BR Ackley Improved) is essentially a 6mm BR that has been Ackley Improved, mostly by having a 40° shoulder instead of a 30° shoulder like in the standard BR case. This increases case capacity while retaining the long neck of its parent case. The 6mm BRA is a very accurate, easy to load, and very efficient cartridge; able to send a 105gr class 6mm bullet at speeds around 2,800-2,900 fps with a relatively low powder charge in the low 30 grains.

The Alpha 6mm BRA brass uses Small Rifle primers and ships in 100 count custom Alpha Munitions plastic cases with perforated bi-layer foam for protection of cases during shipping and can be used for loaded ammunition.

The 6mm BRA cases also feature Alpha's Optimized Case Head Techonology which improves primer pocket life and pressure containment for extended brass life.
