Wheel weights are no longer made of lead,mostly Zinc but the Zinc ones will float to the top in the Lead.Don't get your pot too hot or the Zinc will melt and ruin the lead.Make sure you keep water away from the hot lead because it will cause a steam explosion.If you can find old water pipe or roofing lead scoop it up.
I cast bullets for the .300 blackout. Mainly subs though. I powdercoat them and just have to give my barrel a good cleaning every 500 rounds or so. Feel free to ask any questions.
The main piece of equipment i thing you really need is a good case guage. I made all my own brass, and with running cast bullets, theres alot to be out of spec so having a sheridan case guage is a must IMO and a solid buy at $60 to save yourself some time trying to figure out whats wrong.
It is foolish and wrong to mourn the men who died. Rather we should thank God that such men lived.
