Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge Unprimed Rifle Brass for .22 ARC is manufactured to a match-grade standard that Peterson holds throughout its entire production process from small batch manufacturing lines through final quality control inspection. Each case uses a small rifle primer pocket with a small flash hole measuring 0.060 inches in diameter a detail reloaders should note since it differs from the larger 0.080 inch flash hole found on Peterson s large rifle primer cases. This smaller flash hole requires an extra small or undersized decapping pin when depriming a detail worth keeping in mind when setting up dies for this brass. Consistent case dimensions and wall thickness from Peterson s manufacturing process translate directly into more uniform charge weights and seating depths at the reloading bench. As unprimed brass this product is intended strictly for handloaders assembling their own ammunition and is not a loaded cartridge ready to fire out of the box. Peterson s stated goal is to maintain match-grade consistency all the way from their production floor to the reloader s bench and ultimately to the target and that philosophy is reflected in the attention paid to every case in this box. Reloaders working up precision loads for the .22 ARC cartridge benefit from the reduced case to case variation that comes from Peterson s quality control process. The Peterson Cartridge Unprimed Rifle Brass in .22 ARC is available for sale at GrabAGun for handloaders who want dependable match-grade brass for their reloading bench.
