Description
Packaged 50 factory new WINCHESTER item #WNU3040 unprimed 30-40 Krag brass rifle cases.
History: Once considered a small bore rifle cartridge, that was in 1892 when the U.S. government replaced the 45-70 with the 30-40 Krag. Ballistically identical to the 300 Savage and the inexpensive availability of war surplus Krag-Jorgensen rifles promoted the cartridges popularity in the hunting world at one time
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.
