$20 gets you a complete aluminum replacement mold. Can’t get parts for a steel mold for that. Many of my muzzleloading molds are Lee aluminum ones (plus I have a number of TC Maxihunter and Maxiball molds that are aluminum), but I also have quite a few steel molds, conical and RB. No real complaint about steel or aluminum molds. They all seem to work.Only problem I ever had with aluminum molds is gauling of the blocks by the sprue plate. Just annoying, not a huge problem.
