Is anyone using walnut shells in their tumbling? Is yes, would you mind describing your recipe? Are they used dry?

I reload cartridges and use walnut shells dry in my rotary tumbler to clean and polish the cartridge cases. I would not use them for rocks because they are to soft, even if used dry.

I use the Harbor Freight course walnut shells for cleaning and burnishing in the vibes.........if the stones don't have that eye popping ice cube look after final polish. I let the stones tumble dry (after everything has been washed, scrubbed and dried), for up to three hours. That is if necessary.........nothing can replace the proper previous cycle stage prep and polish. But the walnut has helped with the final cleaning of Cerium Oxide in particular.........mostly on Agates and Jasper, not so much on quartz or crystalized based material.......just my experience.
Note.......it works fantastic on copper, nickel plated shell casings........if one reloads.
