Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge brass for the 6mm Creedmoor cartridge is manufactured to a Match-Grade standard a benchmark Peterson holds from its small batch production lines through final quality control inspection. Constructed from brass each case is built for reloadability allowing handloaders to reuse cases across multiple firings when properly maintained. The small rifle primer configuration pairs with a 0.060 inch flash hole smaller than the 0.080 inch hole found on Peterson s large rifle primer brass. Reloaders working with this brass need an X-small or undersized decapping pin to deprime the cases correctly. Consistency from case to case is central to Peterson s manufacturing process helping handloaders achieve more uniform neck tension case capacity and primer seating across an entire batch. This is unprimed brass intended strictly as a reloading component not a loaded cartridge so primers powder and bullets must be supplied separately by the reloader. Each pack contains 50 cases giving precision shooters a manageable quantity to prep and load in a single reloading session. This 6mm Creedmoor brass from Peterson Cartridge is available for sale at GrabAGun for reloaders pursuing match-grade consistency in their handloads.
