Simple, a manual, Lyman makes a god one. Next you'll need a heat source. You can either use a pot heated by propane or get an electric pot available from various dealers. A dipper is next if not using bottom pour electric pot. Needs to be big enough to fill the mould. If you get a bottom pour electric pot you can do without a dipper. Next is a mould. I like Lee moulds, especially the 6 cavity ones for pistols. If using a bottom pour pot, you can get a good rhythm going with two moulds, filling one, dumping one. Wheel weights make good bullets as is. After melting lead, discard iron clips then drop a peas sized piece of candle wax into the melt and stir deeply, throw away that which floats to the top. Any water that gets in the pot is a BIG DANGER. It immediately turns to steam and blows molten lead around your face and body. Next is a way to lube the bullets you made. Most simple and very effective is Lee Liquid Alox. Place bullets in a plastic tub, sprinkle on some alox, shake, shake again every 10-12 hours until dry. Generally, bullets don't need to be sized if shot through a revolver. Auto-loaders can jam if the bullet is oversized and may need to be sized. If you feel a need to size, get a Lee sizer for the caliber you want. Cast in a well ventilated area and enjoy the "free" bullets you just made.
