I cast a little bit for my muzzleloaders. If I ever get serious about reloading it would be interesting to try casting some others, but some 308 handloads are all I reload. It's a lot of fun to cast lead balls. The only store bought equipment I use are the molds. The lead gets melted in an old frying pan, a small stainless steel ladle that is too small for any use in the kitchen pours the lead, and the skimmer that I use I made years ago for casting aluminum and pot metal.
You can use the side burner on your grill, a really good hot plate, or if you don't mind sleeping outside (alone :shock: ) the kitchen stove.
Don't forget the goggles, face shield, welding gloves, heavy boots, common sense etc.
