I have been pouring lead most of my 61 years here on earth. Ya dont have to invest a ton of money on supply's if you are resourseful. I use old cast iron dutch oven pots. Use a small cast iron pot to dip and pour with. Ya can use any heat, either electric or gas heat. Keep the heat low to prevent over heating of your lead. The pricey part is buying your molds if you choose market style molds. I always pick up spent lead in slugs, bullets, decoy weights, Etc. Full metal jackets have lead cores. If you pour split shots, find a retired plumber, they always have soft #1 stashed away in the barn they will sell Yard sales have been a great place for me to find cheap lead but they rarely set it out. Ya have to ask if they have lead willing to sell..,,, Remember,, Safety is #1,, never have any liquid what so ever around you melting/pouring area. Dont even let a drop of sweat hit it and ventalation pulling fumes away from your face is a must.
