I tumble - resize - tumble. I tumble the 2nd time to get the spray lube all off. I use only walnut media now as I got tired of trying to shake allthe corn cob mediaout of my cases and having to pick the stuck hunks out of my flashholes. I use a Lyman's 1200 Turbro Pro with auto flow.
I do the same, and tumble one more time after trim and chamfering with media that is set aside just for the final tumble. The cleaner your brass is the less likely you are to have problems with your dies.
