I was casting some some bullets the other day. The lead came from melted down used wheel weights. The lead was melted down into a big pot, skimming off all of the clips and that kind of thing, and then poured into ingots. The ingots were dropped one by one into the caster.
The temperture seemed to be okay, but we were still getting some frosting. Usually around the center band of the bullet. (200 gr. .45 SWC) Playing with the temp a little bit did not really change that.
Then the spout started getting clogged. Cleaning out the caster, a brittle crumbly metal was found. It seemed to be heavier than the lead since it sank to the bottom, and it may melt at a slightly higher temp, since it did not really clog the spout until I turned down the temp due to the frosting.
So does anybody know what this stuff is? I made up about a thousand bullets before this discovery. Most of them look just fine. I've set aside the frostiest ones for future testing, but before I do that I wanted to see if somebody here had an idea.
