The wet pins do stick to the cases. I use a media separator with the bottom half filled with clean water. A few turns and the pins drop out.
I suspect you could dump the mesh bag with cases in a bucket of water and stir them around to get a similar result.
Here's what I've got so far. The 45acp was wet tumbled with Dawn soap, NO pins, NO lemishine. It was tumbled for 3 hours. It also had some 357 brass in with it, the other drum (done the same way) had 38's in it. None of these were deprimed yet. (Bent pin) The 38 & 357 look the same, I just photographed the 45's because it was easier to see inside.
The 9mm brass was dry tumbled in a Lyman Pro Magnum for 13 hours with walnut media. 1 hour to clean it a bit so I could deprime it. Once deprimed it went back in for the remaining 12 hours.
My depriming pin came today and the stainless tumbling pins will be here tomorrow. When they get here I'll tumble half of the 45's again with Dawn, Lemishine and the SS pins. I'll do comparison pictures again after that.
It was about 6:30 pm and not very sunny out.
45acp - Wet with Dawn, no pins
9mm - Dry tumbled, walnut media
Both
There is only a slight difference with the wet tumbling edging out the dry. I'm sure that gap will widen once the SS pins come into play and they get deprimed.
I do need to look into alternate containers for the HF tumbler. The rubber ones are nice and quiet, but as you mentioned are a bit of a pain.
It is kinda par for the course at Walmart. I doubt anybody even gives you a second look!
What are you doing with the lead contaminated waste water after tumbling? I can't imagine it would be good to pour down the drain or even legal if on city sewer.

On page 292 you find lead. The reportable quantity for lead is 10 lbs per release. While I'm not sure about how much lead actually exists in spent brass, I suspect you may not wash 10 lbs of lead down the drain in a lifetime. What lead does make it's way into the sewage plant will settle out in the processes.
I was going to make a comment on this as well, but MemphisR32 beat me to it. Even if there is a regulation about how much you can dump at once, it can't be a good thing to have 100's of INGO-ers dumping lead-contaminated water down the sink into the White River. Not sure if it is any better releasing it into the air and then into the landfill when using the dry tumblers...
I would argue that there is more lead released into the environment by shooting than what is left in your brass. No data, just my opinion based on my understanding of the physics of the thing.
Hopefully your sewage is not pumped directly into the river. The normal settling procedures employed by most sewage plants would trap most, if not all the lead collected.
You're probably right...
I am sure some (a lot?) settles in the pipes along the way as well.
No matter how we slice it, lead is nasty stuff, and I guess I worry about it. Not a tree-hugger, but nonetheless...
