Hornady Unprimed Brass Cases .223 WSSM 50/Box

The Hornady Unprimed Brass Cases in .223 WSSM (Winchester Super Short Magnum) are premium empty cartridge cases built for handloaders working with this short, high-performance rifle round. Manufactured by Hornady, these unprimed cases give reloaders an excellent foundation for assembling accurate, consistent ammunition.

Each case is produced to Hornady's tight tolerances, delivering excellent uniformity in wall thickness, weight, and internal capacity so seating depths, case neck tension, and overall ballistics remain consistent from one round to the next. That uniformity is critical when developing a load for the WSSM platform, where small case-to-case variation can translate directly into shifts in velocity and pressure.

Sold as a 50-count box, this product (Hornady MPN 8617) is the same brass that serious .223 WSSM reloaders rely on for case prep, resizing, and loading. Five boxes per case make it well-suited for high-volume reloaders or those preparing multiple loads at once.
