i can give you a bit of instruction on how to cast your own. what calibers are you looking at? i found that Lee makes some very good, very cheap, very easy to use molds. i have four Lee molds so far, they are great. you will need to wear jeans that go over some good leather boots, safety glasses, ventilation, your mold(s), lead, something to ladle it into the mold with, lead, some cotton rags to dump your freshly cast bullets onto, and a way to melt the lead. here's a link to some bullet molds, Dixie Gun works has tons of them

it's a pretty easy way to go because you don't have to deal with propane, scrounging a match so you can light the burner, the lead doesn't get overheated, you don't have to keep buying gas. you just plug it into an outlet, put your lead ingots into the crucible, turn the thing on, and go do something else for a while. the lead seems to stay a pretty consistent temperature as far as i can tell.
also, make sure you use soft lead for muzzleloader bullets. don't use wheel weights, make sure it's pure lead. if you use hard lead for muzzleloader bullets then you will have problems. balls and bullets will be hard to seat in a cap and ball, skirts won't flair in a Minnie ball to engage the rifling so they will hit sideways, stuff like that. but for smokeless you can use hard lead. you can also use it in saboted bullets, and anything used with a patch. it's really easy once you get started! good luck!
