Guys get lead to pour from all different sources. One of the best that I have heard of are auto repair and brake shops. They seem to be able and willing to provide a good amount of old wheel-balancing weights. I've gotten into tying my own bucktails this year as well, but I buy the lead heads. I've done some reading up on the process of molding lead and it seems to be a bit too involved and dangerous for my liking. Unless you're going to be making massive amounts, lead heads of all shapes and sizes are available at reasonable prices especially at the various fishing shows and flea markets. This is a topic that has been discussed a few times here. You can do a search on the discussion boards for "lead" or "pouring" or "pouring lead" and I'm sure that you'll come up with a few helpful posts. A great book covering all types and phases of lure, jig and tackle making that was recommended to me by many members here and eloquently reviewed by our own Jerry Vovcsko (Jerryvov, this boards moderator) is "The Complete Book of Tackle Making", you can view or buy the book at Amazon.com and copy and paste the link below to read Jerry's review....
