My younger son showed up with some salvaged lead, so we spent the cool morning hours smelting lead to make into bullets. Out in the backyard, with plenty of ventilation, we started melting about a hundred pounds of dead-soft lead and about 40 pounds of old wheelweights that I had laid back.
A picture from a little farther out, of the same set up.
As we melted the lead, we cast it into ingots. I've got hree ingot molds, one small Lee mold, and an old cast-iron muffin tin that we use for dead-soft lead. And, an old cornbread-stick mold that we use for harder metal, like magnum pistol and rifle bullets. The alloy is different, and by simply looking at the cast ingot, we know what alloy we're dealing with.
All in all, I figure that we smelted a hundred pounds of lead this morning. At an average of 150 grains per bullet, that's better than 4600 bullets that we prepped today. Not bad for a couple of hours work on a Saturday morning.
