Have a pretty large inventory of lead ingots, 3K+, and plenty of "ore", another 1K, to process. Have been using round muffin ingots for about 95% of my production. Thinking of selling some lead as I process my intake and wondering about what ingot best for packing in the typical flat rate boxes? Where would these ingots molds be available? I have seen the molds done with the angle and channel iron. Is there a commercial source for them? Or get made locally by a metal shop/welder etc...? I did a survey of the vendor section but didn't see any ingot molds, did I miss something? Plus better ingots would stack/store better than the muffin ingots. Any information appreciated. Thanks, 10
