Peterson Cartridge Unprimed Rifle Brass Features Peterson Cartridge builds every case to a Match-Grade standard maintained from small batch production through quality control ensuring consistent wall thickness and case dimensions. This .25 Creedmoor brass is designed for small rifle primers giving reloaders a reliable foundation for precision handloads. The small flash hole measures 0.060 inches in diameter notably smaller than the 0.080 inch flash hole found on Peterson s large rifle primer brass. Reloaders need an X-small or undersized decapping pin to properly deprime these cases a detail worth noting before loading dies are set up. This component brass ships unprimed and is intended strictly for handloading not as a finished cartridge ready to fire. The 500 count quantity gives dedicated reloaders enough brass to work through load development and ongoing production without frequent reordering. Peterson s attention to consistency helps extend case life across multiple firing and resizing cycles a key factor for shooters chasing accuracy at the bench or in the field. For .25 Creedmoor shooters who demand match grade brass from a trusted name in premium casings Peterson Cartridge delivers a dependable component.
