RCBS Formula 2 Corn Cob Media for dry polishing (RCBS part no. 87068) is a treated corn cob media that works in both Sidewinder and Vibratory case cleaners, giving reloaders an alternative to walnut shell for dry tumbling. The polish additive is individually packed within the box, so a reloader controls exactly how much gets mixed in rather than following a fixed ratio. Sold in a 4-pound box, this corn cob option tends to produce a slightly finer polish than walnut media, which some reloaders prefer for a brighter final shine on their brass.
