Peterson Cartridge .243 Winchester Brass Rifle Cases 50/Box

The Peterson Cartridge .243 Winchester brass rifle casings are unprimed, match-grade reloaders' brass produced by a family-owned USA manufacturer long respected for tight tolerances and batch-to-batch consistency.

Engineered specifically for the .243 Winchester cartridge, these casings are built around the Small Rifle Primer configuration and are sold as 50 cases per box, with 10 boxes per case (500 cases total). Each casing is sized, trimmed, and inspected in-house at Peterson's American facility to deliver the precision handloaders expect from a premium brass maker.

Peterson designs, produces, and tests every lot domestically, giving reloaders repeatable case dimensions, uniform wall thickness, and consistent internal capacity - the foundation for tight groups at the range. Whether you're loading for varmint hunting, target work, or precision rifle competition, this brass provides a reliable, accurate platform for handloads in the popular .243 Winchester cartridge.
