They cast very nice. That range lead I recycled into ingots is pretty hard I'll admit (I don't have one of those testers to say exactly how hard) I made about 100 .490 round balls so far. I was just playing with my mold, learning the ropes. I haven't fired one yet. Now that I have some pure lead, I may go ahead and remelt those round balls and cast new ones using the softer lead.
I'm shopping now for a .454 round ball mold for my C&B revolver. When I finally get that I'll be using the soft lead for sure.
