The Hornady Unprimed Cases in .223 Winchester Super Short Magnum (brand part no. 8617) fill a real gap for handloaders running this short-magnum cartridge, since factory brass for it has become harder to source. Hornady built this brass to the same tight-tolerance standards as the rest of its case lineup, so reloaders get proper bullet seating and consistent pressures without hunting down surplus components. Each box holds 50 unprimed cases, packed five packs to a case for reloaders who want to stock up on a cartridge that is otherwise tough to find components for. If you shoot .223 WSSM, this is one of the more reliable ways to keep your bench supplied.
