MEC Brass Prep Tumbling Media 14/20 Grit - Ground Corn Cob - Multi-Caliber

The MEC Brass Prep Tumbling Media is a 14/20 grit corn cob cleaning media designed to polish and decontaminate spent cartridge brass in a vibratory tumbler. Made from ground corn cob, this dry media scrubs away residual lube, dirt, and oxidation from your fired cases, leaving a clean, polished finish ready for resizing and reloading.

Sold as a single unit from MEC's Corn Media series, this tumbling media is rated multi-caliber, so the same media works whether you are processing pistol brass or rifle brass. The 14/20 grit size is intended for everyday brass preparation in a home reloading shop using a vibratory tumbler.

Add the media to your vibratory tumbler along with your cleaned cases, run the cycle, and separate the polished brass from the media. One unit of MEC's Brass Prep corn cob media provides the supply needed to keep your brass ready for the next reloading session.
