one thing i wish someone would tell me how to do, but i want to make a duplex load bullet. Real hard base, soft lead front.
I use two pots, one for pure lead plus a tiny amount of tin, and another for WW alloy. A pistol case makes a great dipper for the pure lead, depends on the size of bullet but often a 9mm or .380 case works well. Wrap a piece of baling wire around the case rim for a handle, and adjust case length so you'll use a full case of lead every pour.
You want to get the mold hotter than you normally would; the idea is to keep the pure lead nose liquid or close to it while you pour the other alloy on top. Heat up the mold past the point where you get frosty bullets from WW alloy.
Pour the pure lead in from the .380 case dipper, then the WW alloy right away. The mold will take longer to cool enough to drop the bullets, so it's a slow process. If desired, water drop or heat treat the bullets, the nose will stay soft.
