Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge Unprimed Rifle Brass in .243 Win is held to a match-grade standard throughout manufacturing from the small batch production lines to the quality control department that checks each case before it ships. That discipline matters most at the bench where uniform case dimensions and consistent wall thickness translate directly into uniform neck tension and more predictable pressures across a batch. Built around a Large Rifle primer pocket this unprimed brass gives handloaders full control over primer selection to fine-tune ignition characteristics for their specific powder and bullet combination. Every case is reloadable letting a shooter track case life and rework the same brass through multiple firings while holding to the same tight tolerances. Brass construction resists the wear of repeated resizing and firing better than cheaper alloys which is why Peterson Cartridge builds its reputation on durability as much as accuracy. A handloader working up a long-range .243 Win load benefits from starting with cases that are already consistent since it removes one more variable from the equation before powder and bullet ever enter the picture. This 50-count box is sized for a standard reloading bench routine giving a shooter enough brass to prep prime charge and seat in one session. From the production line to the target Peterson Cartridge markets this brass as the standard reloaders can carry all the way through their process.
