I've come into some old shot that has been sitting around in open cans for years. When I poured it into some shot bags there was a lot of lead oxide dust floating around. I'm not worried about dying tomorrow because I was in the same county as the dust but is there a way to get rid of it? I know shooting it out of my smoothbore will do the trick so maybe I'll leave it at that but I would like to make the shot look better for esthetic and social reasons.
