Default Lead Dust From Firearms Can Pose A Silent Health Risk

http://www.npr.org/sections/health-s...nt-health-risk


Firearms using lead ammunition spray lead dust out of the muzzle
and ejection port when fired.

Firearms safety is key for people who use weapons at work or for recreational shooting. But one risk has been little acknowledged: Lead dust exposure.

In a standard bullet, a solid lead core wrapped in a copper jacket sits atop a stack of gunpowder and lead primer. When the gun fires, the primer ignites, the gunpowder lights, and some of the lead on the bullet boils. When the casing snaps out of the ejection port, lead particles trail behind it. As the bullet hurtles down the barrel of the gun, a shower of lead particles follows.

If a gun range isn't ventilated well, lead dust collects on shooters' clothing and hands and lingers in the air, where it can be inhaled. The more people shoot, the greater the risk of being exposed to dangerous amounts of lead. It becomes an occupational hazard for weapons instructors, police and defense personnel.
The rest at NPR.

No, it doesn't; the copper jacket prevents that. Who writes this crap?

The primary cause of lead exposure when shooting jacketed bullets is the lead azide in the primer, and this is pretty much obviated with ventilation.

Shoot in the open, or in a well-ventilated range. Wash your hands after you shoot.

The article is trying to pin the problem on guns, when the problem is simple risk abatement.
