Lyman 7631320 Corn Cob Plus 10 lbs Resealable Bag - Premium Brass Cleaning Media

Lyman Corn Cob Plus media is a treated corncob cleaning compound designed to restore fired brass to like-new condition in a tumbler. This 10-pound resealable bag contains enough media to process thousands of cartridge cases, making it a cost-effective choice for reloaders who run regular cleaning cycles. The corncob substrate is treated to enhance polishing action on fired cases, removing carbon, powder residue, and discoloration that accumulate during shooting.

Whether you reload small batches or process cases in volume, this media pairs with tumbling equipment to deliver clean, polished cases ready for sizing and repriming. The resealable bag design lets you store unused media safely between sessions, extending the working life of each batch. Reloaders appreciate corncob media for its gentleness on brass—it cleans without the harshness or mess of other abrasive compounds—and for the uniform results it produces across different case types and calibers.

Because the corncob breaks down gradually over hundreds of cleaning cycles, this 10-pound supply represents weeks or months of regular reloading prep, depending on your caseload and cleaning frequency. For shooters committed to hand-loading ammunition, a reliable supply of quality media is as essential as your press and dies.
