Description
50 factory new Winchester unprimed 375 H & H Magnum (375 Holland & Holland Magnum) brass rifle cases, packaged from bulk.
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.
HISTORY: Introduced in 1912, since then the cartridge reputation was initially earned in Africa and then later Alaska.
