Hornady Lock-N-Load Brass Tumbling Kit

Hornady's Lock-N-Load brass tumbling kit covers the cleaning end of the reloading process, where fired cases get carbon and range grit taken off before they go anywhere near a sizing die.

Clean brass is part cosmetic and part practical. Dirty cases carry grit into a die, grit in a die scratches brass, and over enough cases it marks the die itself. Cleaning also lets you actually see a case during inspection, which is when a split neck or a loose primer pocket turns up. The kit is sold as a package rather than as separate pieces, so confirm the contents against what is already on your bench before ordering.
