I am a little crazy about making perfect ammo so my process is as follows:
(1) Dirty, fired brass goes into the wet tumbler for 30 minutes to clean
(2) Brass is removed from tumbler and dried
(3) Lube with lanolin and alcohol and run through a prep toolhead with only a standard resizing die and a U-die
(4) Brass is polished in the wet tumbler, lube removed
(5) Brass is removed from tumbler and dried
(6) Load ammo, no need for lube as all sizing is already complete
This is way overkill and obviously takes much more time than is required. I enjoy spending too much time loading so it's not a chore for me. This process produces perfectly clean, lube free ammo and keeps my hands and press much cleaner so I prefer it, brass marking is much more effective on lube free cases as well. The same results, minus the sparkling clean press, could be achieved by dry tumbling loaded rounds as many have described above. I would just dry tumble after loading if I didn't shoot PD JHPs that pack full of media when tumbled.
