This 7lb box of corn cob media is dry tumbling media for cleaning fired brass cases before sizing and reloading. Corn cob is a naturally gentle abrasive that polishes brass to a bright finish without the more aggressive cutting action of walnut shell media, which suits reloaders who want clean, attractive cases without excessive material removal. Tumbling is the economical first step in preparing brass: it clears the grit, grime and residue left after firing, which otherwise gets embedded in the case surface and can transfer into your sizing dies, scratching and marring every case that follows. The same grime accelerates wear in a chamber and feeding system if it isn't removed before the case goes back into a loaded round. This box suits standard rotary and vibratory dry tumblers, and the media can be reused across a number of tumbling sessions - just expect its cleaning action to fade with use, at which point it's worth topping up or replacing.
