Same here...big fan of wet tumbling. Here's the 3 biggest things I've learned along the way:
1: I got tired of having to visually inspect every case for bridged pins. Using the FA pins that came with my tumbler, it seemed like I got stuck pins on every batch. The shortest pins would bridge in Large Primer Pockets and others would bridge across the necks of .308 and 6.5mm cases. I switched to the Southern Shine chip-style media and haven't looked back. I have never had even a flake of the SS media get stuck anywhere. Best thing I've done for my wet tumbler.
2: If you want really nice results, particularly when cleaning truly dirty range brass, tumble with just soap for a half hour, drain the filthy water, and refill with clean water and soap/lemishine. I think that with most people who end up getting mediocre results when wet tumbling, it's either from expecting dirty water to get your brass clean, or water quality/hardness issues.
3: I used to use Dawn dish soap and a quarter to half teaspoon of lemishine. Particularly on pistol brass, I found I was needing a lot of effort to pull the belling/powder funnel out of the brass on my Dillon. That's the downside of having brass that is TOO clean. I switched to an automotive wash & wax soap instead of Dawn and it leaves the slightest coating of wax on the brass. This makes it easier to load (both belling and bullet seating) and the light coating keeps the brass shiny for much longer than ultra-clean brass alone. Dry tumbling after wet tumbling also works, with a little nu-finish or other polish/wax, but it's an extra step that I'd prefer to avoid.
Enjoy your new tumbler!
