Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge Unprimed Rifle Brass is built to a match grade standard that Peterson applies from its small batch production lines through its quality control department. Each case is annealed at the mouth and neck a process that relieves brass hardness in that zone so cases resist cracking and hold consistent neck tension over repeated firings. The brass is beautifully polished before packaging giving handloaders a clean uniform case to start their reloading process from. Multiple quality inspections are run throughout manufacturing which is the kind of control that keeps case to case variation low for precision rifle shooters. This brass is cut for small rifle primers featuring a 0.060 inch flash hole rather than the 0.080 inch flash hole found on Peterson s large rifle primer cases so reloaders need an undersized decapping pin to deprime it properly. It ships unprimed and as a component only with no primers powder or bullets included intended strictly for handloaders building their own .308 Win ammunition. Reloadable case construction means this brass can be run through a full reloading cycle multiple times when properly maintained. Fifty cases per box gives shooters a manageable batch size for load development and precision rifle reloading at the bench.
