If you don't need it, don't use it. What brand(s) of brass are you using?
The stuff I am using at the moment are Win, Rem, and Magtech for the .410 but I do add some cull cae=ses to increase the tumbler load when I only want to clean a couple dozen cases. I have read that you don;t use much lemishine so I have been trying about a 9MM case size measure. I have also read that some guys do all their cleaning without lemishine, then run a fresh tumble WITH the lemishine only for 10-15 minutes to get a better shine. Haven't h]tried that yet.
