I am thinking of trying stainless steel media after seeing some of the pictures posted on this site by a member of brass that looks brand new.

Has anyone tried this with a Lyman or a Franklin Arms type brass cleaner? Will it wear one out faster?

On a related note, has anyone used a rock tumbler for a brass cleaner? I read on another forum about a shooter that swore by a metal rock tumbler he bought from Harbor Freight.
