Peterson Unprimed Rifle Brass (Peterson Cartridge part no. 40083-R) is chambered for 338 Winchester Magnum and sold unprimed in 50-count bags. Match-Grade is the standard Peterson holds through the entire manufacturing process, from its small-batch production lines through quality control, and it is the consistency precision handloaders rely on to maintain accuracy all the way to the target. Because this brass ships unprimed, reloaders have full control over primer selection and can build a load from the ground up rather than working around a factory-installed primer.
