Is there such a thing? Looking to cast for 45acp, 30-30, 45-70 nothing crazy. I am wondering if there is a magic mixture that can fill all my needs? Kind of envy some of you guys that have time for your experimenting. Hoping to alloy all that I find in ready to use ingots. Limited time will barely have time to cast shoot and hunt. Figured air cool for pistol calibers and water drop for rifle rounds?
