Remington cartridge casings are precisely crafted from brass that has been deliberately alloyed to offer an interior volume that is always just right and resistant to case stretching and brittleness. Primer pocket tolerances are maintained at.001″ and case neck annealing is carefully watched to provide easy resizing and longer reloading life. unprimed, fresh brass. This ammo is not loaded. Before loading, full-length brass should be sized, trimmed, and chamfered.
Brass Preparation: Occasionally, you may find that a few case mouths on bulk rifle brass are “out of round” or have a little ding below the shoulder. After the case mouth has been annealed, these flaws appear during the final tumbling wash process. Brass producers are aware of the impact on case aesthetics and have taken steps to lessen it, however denting may still happen due to equipment design.
Special care must be taken to lubricate the cases before sizing them if you’re utilizing nickel-plated brass. Because nickel plating is more difficult than brass, it takes more work to size the casings. Invest in a stuck case remover if a case gets stuck; avoid using pliers, screwdrivers, or other common household items as they could harm your sizing die.
