RCBS lube. A little bit into a large Ziploc bag. Dump in your clean brass, (wet tumbled/washed/dried). Close and knead for a few minutes. Dump into a clean bowl and set to sizing. Wash off in hot water.
Close the bag up to keep the lube inside clean. I usually get 200-300 .357 cases lubed before I need to add more. One little bottle of the stuff lasts me for thousands of cases.
I've even used it when crunching .223 brass down to make .22-3000 Lovell, (.315 base diameter) which is a hydraulic press job. Don't see any advantage in the waxes. Stuff is cheap enough that I've never even thought about trying to make my own.
STP is almost impossible to get off surfaces without heat and solvent. That's why we used it 50-50 with motor oil as assembly lube when I was building race engines.
nb. I've always assumed that RCBS was mostly lanolin. Am I wrong?
