I am cleaning up the reloading room and found some red media (polishing) from Thumlers Tumblers that a friend gave me. I ran some cases through it and it left red residue on all my cases. I cleaned them off, one by one with a rag and loaded some. I now have red dust in my gun, magazines and on the press. Is this what I always hear people talking about the dust and dryer sheet threads? I never had this trouble with the Lyman treated media. Should I just dump this stuff and go back?
