zoid 24 Posted December 21, 2011 Is there any particular sign that your media needs to be replaced? I noticed after some time (pretty long, almost a year, 1000s of casings) that black stuff was on my casings after being tumbled. I wasn't sure if that was worn down media or what. I poured in some fresh media and mixed it in what was already there. Seems to bring the brass to a good shine again. Just wondering if there is a casings count, time limit, on when it should be replaced and signs to look out for when it is worn. Quote Share this post Link to post Share on other sites
PeteF 1,044 Posted December 21, 2011 When the brass has that black film on it is when I change the media. Not really on a round count, as depending on where (indoor vs outdoor) You shoot and what you shoot will change how fast the media gets dirty. Quote Share this post Link to post Share on other sites
lunker 274 Posted December 21, 2011 I was never able to really get a round count on it. Basically, I found that cleaning started taking longer and longer. Eventually, the brass started to always have a cruddy film on it. That is when I changed media. In retrospect, by that point it was too late and I was just adding gunk to the chambers of my guns by running that brass through them. Oh well. I use stainless steel media and do a wet cleaning now.

Old School 611 Posted December 21, 2011 I only change out 1/2 the media at one time. Add a dryer sheet. Maybe you have too much dope in with your media(polish). Quote Share this post Link to post Share on other sites
