Bags of 50 factory new WINCHESTER 264 Win. Magnum unprimed brass rifle shell cases.
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.
Cartridge History: The 264 Winchester Magnum was the smallest of belted mags offered in the 1950’s and being ahead of its time due to lack of good slow burning powders. Reloading for the 264 Winchester Magnum today can bring about the pull potential with wide variety of powders and quality .264 diameter bullets.
