Question for the collective. I don't cast my own bullets, haven't had a need to as I can usually find what I'm looking for. But, who knows what the future holds. I realize trying to buy the necessary equipment to start casting right now is probably a lesson in futility, just like trying to find small pistol primers. But, if things happen to loosen up it's something I'm considering. I used to be a SCUBA diver and have 60 or 70 lbs of lead SCUBA weights still in my basement. I'm assuming these are probably pure lead. Would they be good for melting down for casting? I realize I'd have to add tin and antimony to increase their hardness. Other than the actually molds it looks like a sizer is necessary and something to lube the bullets, also a way to melt the lead and safely pour it. What is the best way of determining the correct hardness of the lead? I'd be using it primarily for .38/.357 revolver loads and maybe 30/30 rifle loads. Is it worth the investment in equipment if bullets are still available at reasonable prices?
