Lee Precision (one of the owners I believe) told me a while back that he NEVER tumbled his brass. I asked him why and he said several reasons. He said the carbon inside the case helped lube for the resizing dies, he said that it adds to the wear on the brass, and he said it's basically a waste of time unless they're REALLY dirty.
So I took his advice and haven't tumbled since. I have never had a single jam in the rifle (never), and I've never had an issue that I'd attribute to dirty brass in the pistol. I have had extractor tuning issues but nothing related to brass. After 20 reloads, they still plop right in. They aren't pretty but they're not bad either and after all I don't sit and stare at my brass... I shoot it!
There was someone I heard from a while back who mentioned it's easier to see cracks if it's clean. I've had no trouble finding cracks in the dirty brass. If anything maybe it stands out even more because it's more contrasting.
Anyways, I felt this was overall pretty correct (in my experience) with what Lee had told me about tumbling.
