Peterson Cartridge Unprimed Rifle Brass Features Peterson Cartridge brass is manufactured to a match-grade standard held throughout the entire production process from small batch production lines through quality control and on to the reloader s bench. This .22 Creedmoor brass is designed for small rifle primers and features a small flash hole measuring 0.060 inches in diameter noticeably smaller than the 0.080-inch flash hole found on Peterson s large rifle primer brass. Reloaders should note that this smaller flash hole requires an x-small or undersized decapping pin to deprime the cases properly. Consistency in case dimensions and flash hole sizing helps reloaders achieve more uniform ignition and pressure from round to round. Sold in a 500-count box this brass gives handloaders a substantial supply for developing and refining loads without frequent reordering. Peterson s commitment to match-grade consistency is aimed at helping reloaders maintain accuracy standards all the way from the loading bench to the target. As unprimed brass this product requires the reloader to supply their own primers powder and bullets to complete a cartridge. For .22 Creedmoor shooters serious about extracting maximum accuracy from their rifle this Peterson brass offers the quality foundation that precision handloading demands.
