I purchaded 500 bullets with some black goo in the lube grooves, may have been bullet lube, but it didn't work very well. I put a couple layers of paper towel in a pan and set the bullets base down on the towel. 200 degrees for mebbe 15 minutes in my toaster oven did the job. No, the paper didn't ignite and cleanup was easy, just toss the paper towels. I prefer this to a solvent dunk/soak...
