For people who do reloading at home and want the best accessories possible, the Berry Manufacturing 400 Vibratory Tumbler Kit 2 is an ideal choice. This particular tumbler has the ability to create maximum cleaning power simply by turning on the switch. With that done, the tumbler does all the work, which results in clean, polished brass. Included in this kit is the actual tumbler along with 6 pounds of corn cob media, brass polishing media additive, and the high-capacity, fully enclosed rotary sifter that prevents the corn cob from flying outside the tumbler.
