I started out with a small cast iron casting pot, maybe 4" deep and 6" in diameter, and a Lyman ladle. Being a lefty I brazed a nut on the opposite side of the ladle and screwed the handle on that side. Used any heat source, mostly a hot plate or gas camping stove. For ease of use and convenience, I now have Lee and RCBS bottom pour pots, with the Lee 20 pound pot getting the most use. The original little pot still gets used on occasion at rendezvous, over coals, to demonstrate casting ball or to supplement my supply. I know some people say that the bottom pour pots don't deliver lead fast enough for the larger balls or bullets, but I have had no trouble with casting 500+ grain bullets. Just make sure your lead and mold are both hot enough.
