Add to the quality of reloaded ammunition by using the M-1 Case Tumbler to clean and polish large quantities of cases quickly and efficiently. Coupled with Hornady’s Tumbling Media, the cyclonic and vibratory action of the Tumbler cleans brass to a brilliant shine. Use the included sifter to separate the polished brass from the media. Running time varies based on the condition of the cases and degree of cleanliness desired. Holds up to (400) .38 Special cases, (180) 30-06 cases, or the equivalent of other like-sized cases.
