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: 30-06 is still one of America’s favorite cartridge to reload for. Economical, ability to shoot bullets ranging from 110 to 220 grains and the wide array of powders available all equates to versatility.
