Casting with Wheel weights?

"I've thought about casting my own bullets, but I'll stick to cigarette smoking ... it's healthier."

Not true. Use decent ventilation, don't eat or smoke while casting bullets or cleaning lead, and wash your hand well before eating or smoking and you won't have any problems.
I cast in a shed with the window open and a fan blowinf from the window toward me. The door at the other end of the shed allows all the smoke and fumes to be blown outside.
At one time, I used to work for a company in San Francisco that sold cast bullets. Usually there were three or four of us working at the same time literally emptying one pot while another pot was melting the next batch of metal. The room was maybe 10x10 feet square, no windows, no ventilation no nothing. We smoked, ate and drank while we were working. While that was many more years ago that I've cared to count,and I have been casting bullets for 54 years, with all the BS about lead and the hazards, I decided to get myself checked out for any problems with lead. It's a simple blood test andit turned out that the lead in my system was well below what is considered normal for a person of my age (70) Even under the more stringent standards for today, the lead in my system is below those levels as well. However, these days I do work using suggested precautions.
I guess my point is maybe there is more to all the anti-lead BS than meets the eye. After all, look at the movement to remove lead from all bird shot and in bullets with California leading the way. Make it illegal to possess lead or lead products and there goes most of the bullets for rifle and for all practical purposes all handgun ammo.
I quit smoking back in 1975. That allowed me more money to shoot and reload and yes, cast more bullets.
With reasonable care, casting bullets is a hell of a lot safer than smoking. been there and done both.
