RCBS Formula 1 Walnut Shell Dry Polishing Case Cleaning Media 5 lb

The RCBS Formula 1 Walnut Shell dry polishing media is RCBS's primary dry case-cleaning media, formulated for reloaders who want fast, aggressive cutting action on tarnished brass before final polishing. Made from ground walnut shells cut to a 12/12 sieve size, Formula 1 is treated with two special cleaning oxides that help strip stubborn case lube residue, oxidation, and grime from cartridge cases in a single run.

This 5 lb carton contains one large bag of the treated walnut shell media plus a smaller bag of non-toxic abrasive polishing compound that you add to the tumbler for a brighter, more uniform finish. The dry, abrasive nature of the walnut hulls makes Formula 1 the go-to "first stage" media for heavily soiled pistol and rifle cases pulled straight from the press, and it pairs well with a follow-up run of RCBS Formula 2 corn cob media for a final luster.

Formula 1 is compatible with both the RCBS Sidewinder and standard vibratory case cleaners, and the universal formulation works across all common handgun and rifle case calibers. The 5 lb carton is a sensible working quantity for the high-volume reloader, and the media can be reused by simply re-adding the included polishing compound as it ages. Brought to you by RCBS, a long-established American reloading brand.
