Peterson Cartridge Unprimed Rifle Brass Features Peterson Cartridge builds its Unprimed Rifle Brass in 6mm ARC to a Match-Grade standard a benchmark the company applies throughout every stage of production from small batch manufacturing to final quality control inspection. This unprimed brass is sold strictly as a reloading component and contains no primer propellant or bullet leaving the handloader in full control of load development from the ground up. Consistency from case to case is central to Peterson s approach since uniform brass dimensions directly affect how predictably a load performs once assembled and fired. Reloaders chasing tighter groups and more consistent velocities depend on this kind of case to case uniformity as the foundation of a precise handload. Each case is sized to accept a small rifle primer matching the specifications reloaders need when prepping 6mm ARC brass for the press. Peterson s stated goal is to maintain that Match-Grade standard all the way from their production floor to the shooter s bench and ultimately to the target which is why their quality control process is built into every step rather than applied only at the end. This 500-count box gives handloaders a substantial supply of brass to work through case prep priming charging and seating without constantly restocking. For 6mm ARC shooters who reload their own ammunition Peterson s Match-Grade brass offers a dependable foundation for building consistent accurate loads.
