Although I did not read all of the posts, I have had the issue you describe.
I found that I had over charged the tumbler with too much brass for the amount of steel shot.
This just makes the brass tumble against itself.
Try reducing the amount of brass. (2 to 2.5 lbs)
Also I use a drop of Dawn and a teaspoon of Jet-Dry
3 hr run time
Might work for you.
