I switched to Barnes this year specifically because I don't want to ingest lead. My dad reloaded his whole life, cast his own bullets, shot lead, played with lead, etc... He just died of liver cancer in May. And he wasn't a drinker.
It's easy to dismiss the warnings when it doesn't kill you immediately. My dad use to shrug it all off, but I tell you, taking care of him while his body shriveled up and died was no fun.
I figure if they don't want you living with lead paint on your walls, why the hell would I want it in my food!
I don't want copper either though... I've cut myself on copper petals while gutting a deer. Scary stuff. I'd be interested to hear others experience with Barnes.
