50 factory new HORNADY unprimed  223 WSSM brass shell cases.

Formally known as the 223 Winchester Super Short Magnum. The .223 WSSM was introduced in 2003 by the Browning Arms Company, Winchester Ammunition, and Winchester Repeating Arms Company.  It is currently one the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second.


Case mouths MAY not be perfectly round from the manufacturing process, this can be corrected by running brass through the size die (always recommended) prior to loading. Residue from the annealing process may leave a stain on the case neck that can be removed by tumbling. Annealing involves rapid heating then cooling to impart the shell cases with the proper hardness to securely hold bullets in place and provides flexibility to expand and contract through multiple firings.
