Used a dry tumbler for 25+ years with corn also walnut media. Changed to wet tumbling with stainless steel pins , cleans the carbon from the inside of the case & primer pockets when spent primer is removed , I use a Q - Tip to dry the primer pocket. Changed to wet tumbling , when talking to reloaders on wet cleaning, at first I didn't like the idea of water. After watching some video's on line. Ordered a tumbler from Harbor Freight for smaller quantities. Ordered the tumblers model B tumbler for larger quantities. Very happy with wet tumbling & glad I did. Check it out before you pull the trigger on a tumbler.
