Casting is certainly the way to go. You’ll never find yourself in this situation ever again, that and the cost ($40/100 + shipping) vs 29 bullets of the same weight for $1 in scrap lead. It didn’t take long to recoup the cost of my cheap Lee equipment and molds, and a custom mold for my revolvers. In about an hour or so I cast up 132 round balls to give each revolver 11 cylinders for a range day. No waiting, no additional expenses as the lead is paid for and no shipping. It’s all win. Look into it at least.
