The Hornady .223 WSSM Unprimed Rifle Cartridge Cases provide a premium, highly consistent structural foundation designed for precision handloaders developing custom ammunition for the Winchester Super Short Magnum platform. These high-grade component cases are manufactured in small, specialized lots to meet strict quality control standards, ensuring excellent lot-to-lot uniformity in weight and internal powder capacity. Every case features precision-measured wall concentricity to deliver proper bullet seating alignment within the case neck and the rifle chamber, which aids in a clean, uniform bullet release upon firing. Every piece is run through an internal pressure calibration test to promote perfectly symmetrical case expansion during ignition while extending the active reloading life of the brass over multiple firing cycles. Packaged as a loose component box of 50 unprimed brass cases, this American-made product features large rifle primer pockets to give competitive benchrest shooters and varmint hunters optimal control over their ignition properties.
