• If you have brass that has not been cleaned after several reloads, or you have some range pickings that are severely discolored from sitting on the ground for a long period of time, the more popular media to use is crushed walnut shell media. Walnut shell media is a more aggressive media than corncob and for that reason it is best used on heavily tarnished brass casings.
