Alpha Munitions Unprimed Brass 6Mm Dasher 100/Box$138.90
Availability: In Stock
The Alpha Munitions Unprimed Brass 6mm GT is purpose-built for reloaders chasing consistency in precision rifle competition and long-range hunting. Developed by George Gardner of GA Precision and Tom Jacobs of Vapor Trail Valley Bullets, the 6mm GT cartridge design optimizes case dimensions to deliver the low velocity spreads and repeatable performance that matter when precision counts. Whether you're loading for PRS-style competition or developing a match-grade hunting load, this unprimed brass gives you the foundation to build ammunition that shoots true.
The 6mm GT's 35-degree shoulder was engineered to feed reliably through detachable magazine systems without requiring modifications or aftermarket inserts—standard .308 Win AICS and AW magazines work straight out of the box. That thoughtful design means less troubleshooting and more time at the range. Case efficiency runs near 100%, allowing you to maximize powder charge optimization with powders like Varget in the 33–35 grain range. Performance expectations are solid: 103–105 grain bullets can reach 3020–3100 fps, while 115-grain projectiles sit around 3000 fps, though your load development will depend on your specific powder, primer, and bullet selection.
These cases ship in 100-count boxes with protective foam inserts designed to safeguard brass in transit and during storage. Alpha Munitions' OCD (optimized case head technology) is incorporated into each case to extend primer pocket life and overall case longevity, even when running higher pressures and velocities. The brass uses small rifle primers, so make sure your reloading setup matches that specification.
