Load them up with Steelheads load and try them out. If they lead badly then try something else, if they don't then you have a good load for anything you want to shoot. Being a bevel base bullet I'd say they will leave some lead in your barrel. One of my favorite loads for commercial bevel base SWC's is 18.5 grains of 2400. It's accurate in both of my Super Blackhawks and my Model 29. It dosen't lead and recoil isn't bad either.
