Might be a silly question, might not. I cast some round balls recently just for giggles, had all those shiny ingots from stick-on ww's and couldn't resist ordering moulds and casting a few shiny little balls. I shoot .54's in a Hawken with a lubed patch but I shoot the .45's in a C&B revolver over a lubed felt patch. I've not noticed any leading but can't help but wonder if I should TL the .45's.
