RCBS Formula 2 Corn Cob Media – Reloading Case Polishing

RCBS Formula 2 Corn Cob Media is a crushed corn cob-based polishing media designed for use in vibratory case tumblers during the final finishing stage of brass preparation. This medium-grade abrasive removes light tarnish, oxidation, and residual powder residue from fired cases, leaving a clean, polished surface ready for inspection and reloading.

Compatible with all standard vibratory tumblers, this media works across all common rifle and pistol calibers. The corn cob formula provides effective cleaning without being overly aggressive on brass, making it suitable for routine case maintenance. Add a small amount of case polish additive to enhance shine if desired. Each container provides enough media for multiple tumbling sessions depending on tumbler capacity.
