Description

50 factory new WINCHESTER unprimed 270 Winchester Short Magnum (270 WSM) brass  shell cases, packaged in older factory sealed blue bags,

The 270 WSM, when introduced in 2002 is an improvement over the older 270 Winchester providing higher velocity with bullets of the same weight, and thus a flatter trajectory and more energy. Velocities tend to be about 250 ft/s faster, in a cartridge that is shorter and can therefore be used in a shorter action for a more compact rifle if desired.

RELOADING PREPARATION:
Brass 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 handloaders expect.
