50 factory new WINCHESTER #WSC25WSSU unprimed 25 WSSM (25 Winchester Super Short Magnum) brass rifle cases.
History: Introduced in 2004 with the concept of doing what the 25-06 Remington in a shorter, lighter rifle. The short fat case design is designed to be a high volume case that imparts a uniform powder burn which yields excellent accuracy and produces very high velocity.
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.
