Description

50 factory new unprimed Remington brass 300 Winchester Magnum (300 Win Mag , 300 WM, 7.62 X 67 mm) shell cases packaged from bulk.

The 300 Winchester Magnum was created to equal 300 H&H ballistics in a cartridge length that does not require magnum length actions, which in return makes rifle affordable to hunters and shooters. A great American 30 caliber magnum and a favorite by many shooters to reload.

RELOADING PREPARATION:
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.
