Peterson Cartridge .270 WSM Rifle Brass, 50-Count

The Peterson Cartridge .270 WSM Rifle Brass (brand part no. 40078-R) is a 50-count box of unprimed rifle cases built for the .270 Winchester Short Magnum, a hard-hitting, flat-shooting cartridge popular with big-game hunters who want magnum performance from a short-action rifle. Peterson is known for holding tight dimensional tolerances case to case, which keeps neck tension and case capacity consistent — two things that matter for repeatable magnum handloads. This quantity is a practical starting point for load development before ordering in bulk.
