Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge Unprimed Rifle Brass in .300 Norma Mag is built from brass material to a match grade standard that is held throughout every stage of manufacturing. A large rifle primer pocket is machined to tight tolerances which lets reloaders seat primers consistently and achieve reliable ignition across an entire batch. The company s quality control department inspects cases before they ever leave the factory so shooters see less variance from case to case at the bench. That consistency translates directly to tighter groups downrange which is exactly what long range .300 Norma Mag shooters are chasing. Each box holds 50 pieces of reloadable rifle brass giving handloaders a dependable supply to build a full batch of precision ammunition. Because this is unprimed brass reloaders control every variable in the loading process from primer selection to powder charge and bullet seating depth. Peterson s small batch production approach keeps the brass accurate and durable through multiple firings and reloadings. This is the right component for reloaders who want match grade consistency built into their .300 Norma Mag ammunition from the ground up.
