I currently have about 1200#'s of soft sheet lead similar to roofers lead I would guess. From what I have been reading it would be kind of expensive to bring this up to a harder alloy. I will be casting strictly for 40 S&W and may do some muzzleloading bullets too but that won't be the issue. So what do I do to get this lead up to usable stuff for 40? Am I just better off trying to sell or trade it off for harder alloy to use? I was thinking maybe just adding some tin solder but this could get expensive and I don't think I can add enough to get it where it needs to be. Keep in mind I am very cheap and prefer to not buy anything expensive . I have hit just about every auto shop in the area to see if I can get wheel weights but as you know that was a lost cause. Not sure what to do next so anybody else have some suggestions?
