Congratulations! You'll never be the same again! As you walk through parking lots, a wheel weight will become a treasure!
Say, you didn't mention what kind of pills you will be casting! Rifle or handgun... it does make a difference on the lube issue.
Also, if using scrap lead, stay away from scrap automotive batteries! The gasses produced when smelting these can be toxic. Also, if using scrap, such as wheel weights, make sure that you smelt them, fluxing liberally, and then pouring into ingots, don't by any means go directly from scrap wheel weights in the pot to pouring bullets! Also stay away from the lead weights that are zinc coated to prevent them from oxidizing... just a hint of zinc will positively ruin a whole batch of good bullet alloy!
Tire stores are a better source than are junk yards when searching out scrap wheel weights. Scrap lead prices are so low right now, that a tire store may even give you a generous quantity these days! The worst they can say is no!
Aslo, make sure you have plenty of ventilation when using your new toys! Also keep the casting temperature under 900 degrees.... lead oxidizes into the air at 900+ degrees very readily. A casting thermometer is not a bad investment to along with your other essentials.
Finally if using gas checks, they aren't all created equal. The Hornady gas checks are of a crimp on design that work the very best of the ones out there for sale. (RCBS gas checks are still made by Hornady), and Gator checks are good crimp on types as well. Lyman checks are only a friction fit, and come off at varying distances from the muzzle.
Lots of new variables to occupy your time, and make you pull your hair! You'll love it!
God Bless,
