Description
Bag of 50 factory new REMINGTON unprimed 300 Weatherby Magnum brass rifle cases ready to reload
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.
