A nice bright and shiny morning found me at a friend's house casting lead ingots and learning some fine points of casting bullets myself.
We used a turkey fryer base and iron skillets to melt the various raw material -- wheel weights, lead pipe, etc. -- into ingots using muffin tins as molds. Each lot was marked as to raw material used.
We ended up with 76 ingots ready to go into the cast pot to be made, eventually, into boolits.
