most bullet lube acts like flux when melted, so re-melting previously lubed bullets is a good way to recycle and improve bullet alloy, yeah it smokes a great deal, but it also causes impurities in the lead alloy to surface and mix as dross where they are easily skimmed off as dross, thus improving the alloy that's left

saw dust, with a bit of bees wax is a very effective flux, bees wax and paraffin both work, but bees wax in small amounts mixed with saw dust preferred, it can remove unwanted calcium, zink etc. flux and stir the alloy frequently to reduce contaminate content before casting with lead from old bullets
