Peterson Cartridge Match-Grade Unprimed Rifle Brass Features Peterson Cartridge Unprimed Rifle Brass in .280 AI is manufactured to a match-grade standard that Peterson applies consistently through every stage of production. Starting on small batch manufacturing lines and continuing through a dedicated quality control department each case is checked before it reaches a reloader s bench. That level of scrutiny results in brass with consistent wall thickness and case dimensions both of which directly affect how uniformly a load performs across multiple firings. Each case in this batch is sized for a large rifle primer matching standard .280 AI reloading specifications. Because the brass is fully reloadable careful reloaders can expect to get several firings from each case before it needs to be retired improving the overall cost efficiency of handloading over factory ammunition. Peterson s commitment to match-grade consistency means less variation in neck tension case capacity and overall case length which translates into tighter groups and more predictable velocities at the range. This is unprimed brass only meant strictly as a reloading component and not loaded primed ammunition ready to fire. For handloaders working up precision .280 AI loads who want brass built to a demanding standard this 250-count box of Peterson Cartridge Unprimed Rifle Brass is available for sale at GrabAGun.
