Just like the Nu Finish added to dry media acting as a sizing lube, the Auto Wash and Wax added to wet tumbling will end any sizing or expanding "hang ups".I have tried wet cleaned brass my dillon does not like them, hangs up on the flair die. Just Adds another step for me
Wet tumbled brass, clean inside, allows a better visual powder check for me.
Not looking to debate methods here, just add some info, use what works for you.
