I am getting rid of an old sandblaster that has a bunch of new fine glass bead media in it. I was wondering if this would be good for cleaning (not polishing) my 22-250 casings???

Thanks!

The only way to find out is try it. I kind of doubt glass beads will be aggressive enough to clean in a vibra-tumbler ( no sharp corners like ceramic cones). Now that I said that it will proably work! Let us know how it works, you could be a genius.

It would probably work but make certain to wash and re wash the brass before loading. All it would take is one glass bead to scratch your die.
I don't think it would be worth it but I aint the one with the glass beads.
