Though I don't like the idea of sizing my cases after annealing without removing that oxidation of the necks so not to put any more wear on the die than needs be or get any damage from that oxidation layer, which is a pretty rough coating. Very often now, after annealing I'll simply take some steel wool and simply give each case a couple twists to clean the oxidation off and then size them, where this is the only cleaning I do other than cleaning the primer pockets with a unfirming tool (the pic below is what the cases look like afterwards). This latter process takes a lot less time than wet tumbling and I find that the results on paper is just as good.
Now I have to try this too! Dang it!
