Knifenoy,
Casting lead bullets is easily learned. Shucks, if I can do it, anyone can. I would suggest reading a copy of the "Lyman Cast Bullet Handbook". Lyman has a website at
www.lymanproducts.com. The handbook tells you everything required to start casting bullets. I mix wheelweights and linotype and melt them in a small pot on a Lyman camp stove. You flux or clean the lead by dropping a small piece of candle wax on the molten lead and the wax will burn. You slowly stir the melted lead with a spoon and skim off the debris and let it drop onto the ground.
To get good bullets requires some practice and if a bad looking bullet comes out of the mold, just put it back into the pot to be remelted. The bullets get better and you develop a casting rhythm. New bullets are soft and need to be carefully dropped out of the mold onto a piece of folded cloth or an old towel. To prevent the mold getting too hot, I use several molds and rotate them. Before you know it, you have made a lot of bullets.
When I get a coffee can of bullets, I call it quits for the session. Then the lead bullets are run through a luber and sizer that swages the bullet and forces lube into the grooves. The bullets get boxed up and are ready to be loads. Hope this explains the process. All the best...
