A couple tablespoons of denatured alcohol (SLX or yellow bottle HEAT) will cause the dust to collect on the sides of the bowl. And the alcohol will evaporate quickly. A single USED dryer sheet, torn in thirds, added to the mix, will extend the life of the media by collecting the dirt/dust.
I use Harbor Frieght fine walnut shell blast media. I pretreat the media with 3 cap fulls of Nu Finish car polish - add and run for 1/2hr before use. My tumbler is an old Dillon CV500.
I tumble before I do anything with the brass. I tumble 223 range brass a second time after primer pockets and trimming. And I sometimes tumble loaded cartridges to clean them up.
If you're just doing straight walled cartridges corn cobb (pet bedding from the feed store) is great. If you're doing 223 I recommend walnut shell.
