I was going to cast for a friends' 45-70, he sold the gun. So I have a new mold I don't need. It's a Lyman single cavity 457125. That's the 500gr RNPB they've made forever. It a current production, factory warranty mold. I could use a PB 200gr .35 caliber mold or a light .30 caliber mold(130-150gr).
