The 6mm Dasher is a popular cartridges based off the 6mm BR (Benchrest) case. It has roughly 10% more case capacity than a 6mm BR and has been popular with Benchrest shooters for a long time and has recently become very popular with Precision Long Range competitors. It’s known for being a very efficient and accurate cartridge that is easy to find really good loads for. The Alpha 6mm Dasher 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.

Each 6mm Dasher 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 at higher than normal pressures and velocities.
