Alpha Munitions Ultra Premium Unprimed Brass Cartridge Cases 6 BRA (Ackley Imp)- Small Rifle Primer Pocket 100/Box

When Alpha Munitions took on the 6mm BR cartridge case, the company decided to make a few changes that ultimately increases the efficiency and longevity of your loaded rounds. The resulting 6mm BRA is an Ackley Improved cartridge case that has a 40-degree shoulder instead of the 30-degree shoulder found on the original round. This increases case capacity while retaining the longer neck, so you can load a 105-grain bullet up to 2,900 fps with a fairly low powder charge. Each 6mm BRA case produced by Alpha Munitions also incorporates the company's OCD with optimized case head technology, which is designed to lengthen primer pocket life, as well as the life of the case overall, even Mfg: Alpha Munitions
