Hi Mike, try some Hornady One Shot Case Lube spray already referenced after tumbling cases, but prior to resizing your pistol brass. Works well and no need to clean it off unless you are crazy with the spray can. Find yourself a smallish plastic tub (~12"x 12" works well) and put clean cases in to cover only the bottom. Spray and aggitate...spray and aggitate a wee more, if nec. Load away. I think you will like it.
I like walnut/Nu Finish for media.
