Selling stuff would kill you on the shipping. We have a lot of fishermen here also who need lead, but most of the serious ones melt their own.

For anyone doing lead melting, lead is toxic to the central nervous system, so use the proper controls. Use the melter only in a well ventilated area, and wear a respirator with a HEPA (pink) cartridge when you are handling liquid (pouring). Don't fire it up in the garage in winter.
