REMOVE THE TARNISH, WEAR, AND TEAR FROM YOUR CASINGS WITH HORNADY ONE SHOT TUMBLING MEDIA.
Hornady One Shot Tumbling Media uses an abrasive media called Corn Cob to clean up your cartridges before reloading. Cleaning out your cartridges is a good practice because any residue or dirt left on the cartridges when reloading causes premature wear out on your reloading equipment. For improved cleaning, media can be treated with a brass polish to help get that mirror like reflection.
