Lyman 600 Accessory Bowl w/Lid. Simply add a little bit of your favorite (preferably brass) media to coat the inside of your cases and tumbling bag and let it soak for the specified amount of time. Then simply pour the remainder of the media back into your (preferably plastic) tumbler container and give it one more quick shake to finish coating the cases. For those of you who want to coat your cases for a few seconds while in your tumbler use the Lyman Turbo Accessory Bowls w/o Media. They drain very quickly and will coat the outside of your cases with a fine layer of either cleaning media or tumbler aid. Best of all they are made of the highest quality materials.
