Wendyj, I started out 58 years ago with a single cavity Lyman mold, Lyman pot and dipper. I still have the all that. A Lee Mold is a good place to start, scrub it well several times under very hot water a toothbrush and Dawn liquid. Dry and then heat it up by the lead pot or burner. Lube with 2 cycle synthetic oil then start casting. Be sure to leave a large puddle of lead on the sprue plate, you will notice a slight dimple on the sprue as it cools. A large puddle helps with good fill out. Remember all the sprue and bad Bullets can all be remelted so you aren’t,t wasting anything with the large puddle. Have fun and do get some cheap Harbor Freight welding gloves.
Be sure to post some pictures on the forum for a critique and helpful suggestions. We were all once where you are now! Tim
