I think you need to catalog them by Lyman mold number to determine what you have. If they're are single cavity molds, I doubt that you'll have much of a business opportunity using them to cast and sell bullets, but the molds themselves can bring premium prices if they're in good shape.Purely a guess but if there was enough demand for odd caliber cast bullets I would think any of the current manufacturers of cast bullets would be offering them.

Also have about 100 lbs of lead. I'm going to be retiring from HP in a couple of year. Looking for something to supplement my income. Start up costs are a minimum.
...just for the simple act of selling a handful of cast bullets? There are no goverment regs on that.
