Some folks seem to miss the major point that most exposure to lead from primers occurs when the primer is fired. Most of the lead and other toxic material is blown out the barrel, out the bolt when it os opened (semi autos) and out the cylinder gap on revolvers.
There has been many "
Scientific studies" as opposed to anecdotal web info that show the routes of exposure to lead
Lead is not absorbed through the skin so wearing gloves does little to nothing. It is absorbed from inhalation, ingestion or through the eyes
If one shoots indoors there is the greatest risk of exposure regardless of how good the ventilation system is. If the indoor range allows lead primers and bullets then you are exposed. It is on your clothes, hair and all your "stuff"
Outdoors when the wind blows in is blowing the toxins all over you, when you sweep up your brass it is kicked up all over,
So how much exposure do you get when you shoot say a AR15 and fire 30 rounds with your face right there close to the ejection port?? A hell of lot more then when you tumble some brass,
Folks don't seem to concern over this?
But then folks get all concerned about dry tumbling with a cover on the unit or when separating the media. Most of the lead is already gone.
Shooting and GSR that gets on you doesn't seem to warrant any concern for some reason??
How phobic are people when the clean their guns (assuming they clean them) all that nasty stuff in the barrel and cylinders??
Wash your hands, take a shower after shooting, and don't eat drink smoke or pick your nose.
Think of all these when you are shooting!
