Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge Unprimed Rifle Brass in .400 Legend is held to a match grade standard throughout manufacturing from small batch production lines through quality control before it ever reaches a customer s bench. Each case measures 0.44 inches in both length and width dimensions as shipped and is built from brass for consistent sizing and reliable reloading performance. The cases accept a large rifle primer giving reloaders the ability to tailor ignition characteristics to their specific .400 Legend load. This level of manufacturing discipline is what separates match grade brass from bulk commercial components and it is why handloaders return to the same batch-tested source rather than gambling on mixed once-fired brass. Small batch runs let Peterson Cartridge hold tighter tolerances than high-volume commercial lines typically achieve so every case in the box starts from the same baseline dimensions. Reloaders get 50 unprimed cases per box enough to assemble a full working batch without interruption. Each case weighs a fraction of an ounce individually and the brass construction allows for multiple reloading cycles when cases are properly inspected and resized between firings. Shipping the brass unprimed means none of that uniformity is compromised by a factory primer choice so the reloader decides which primer best suits their powder charge and bullet combination. Peterson Cartridge built its reputation on consistent accurate and durable brass rifle casings that hold up through repeated firings without stretching or splitting prematurely. That durability translates directly into lower cost per round over the life of the brass since a well-maintained case can be run through a press many times before it needs to be retired.
