Factory new REMINGTON unprimed 8 mm Mauser (8X57 mm) cartridge cases, packaged from bulk , 27 PCS
BULK BRASS : Odd numbers of cartridge cases are the result of bulk bagging. Bulk brass is sold in barrels, generally by weight and it is not uncommon for odd number of pieces remain.
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.
