I've burned up two Lee pots, one a small dipper, and the other a bigger bottom pour. Both served me well right up until their untimely end. Every bottom pour lead pot I've ever owned was a pain. The one I have now is a 20 pound Saeco that I converted to a dipper, because I got tired of trying to stop the perpetual leak. I've worn out several Lee aluminum molds as well. They are great for those just getting started, because you don't have to worry about forgetting them, and having them rust up.
My pet peeve is people that use cookware for casting lead. Absolutely, for sure, some time down the road, after you are room temperature, somebody is going to start cooking it those pots, and skillets, and muffin pans, unless of course you break them when your done, or have them buried with you. For heaven sakes, spend a buck, or two, and buy a cast iron lead pot, if you have to have one that required a stove, or fire.
