The primary cause of lead vapors at a firing range is from the bullet, and not the primer. And yes, with a poorly ventilated range, the buildup of lead vapors can be quite toxic. I remember shooting at the old White Bear range, which had the pistol range in the basement, and the ventilation there (this was probably 30 years ago) was practically nil. After shooting for a while, you would wind up with a sweet taste in your mouth, which was the lead vapor getting into your mouth and lungs.
Both the Ranier and Berry's brands of bullets were created with 100% coverage copper plating to eliminate this problem. FYI - 230 grain 45 ACP "ball" ammo still has an exposed lead base, and can produce lead vapors.
Yes, some Barnes bullets are solid copper, but those are generally for heavy skinned African game, and they are freaking expensive. Not only do you get leadless shooting, but you will also be moneyless rather quickly.
