Don't know if you know anything about casting but you'll need a few things to do it. Other than the obvious-lead and a pot to melt it, you can get away with a simple lead dipper to pour the lead into the cavities once you get the mold up to temperature. Then you'll need to size them, but if you're really lucky they may not need that (if they are much over 0.453 then you may have feeding problems because they may be too wide once seated in the brass). And then you'll need to lube them. It's not hard to do but it does take a bit of learning and some equipment.
