I've been pouring jigs for the better part of 15 years, mostly for Steelhead. In '03 I changed over to lead free using solder I accumulated through samples from solder suppliers. The price on the bar stock has really gone up, but is still a viable option for those with state restrictions which I don't have. They are just a bit lighter, but the fish don't seem to mind. I sell them for $4.50 each or $45 doz and have sold 20-40 doz per year over the past few years. I field test quite a few over the winter as well and it is very rewarding to catch a fish on something you make. This past year, I sent some jigs to a couple guys chasing Walleye, looking for the State record in WA. They found a few over 18 lbs, but didn't find the record. We'll try again this winter.
If I can help you get started, sell you some material, sell you some poured hooks, painted or plain, just let me know via PM.
