If you have a strong vibratory tumbler, it should work, but I would dump several in there and watch before putting a lot with the lid on, this is one good reason to have an old rotary tumbler around, with those rubber or plastic drums, you can even use liquid.
I use to tumble my revolver rounds in a rotary tumbler with newspaper clippings, they came out clean and dry with very slick feel that helped in loading the cylinder, another shooter asked how I them like that and is told him, He came to the next match and showed some loaded rounds that looked like someone had melted the bullets with a torch, newspaper clippings do not work as a medium in vibratory tumbler.
