Obviously, your target will have significant lead exposure most of the time, but at the firing end there's a significant correlation between shooting and having notably higher blood lead levels.
I'm sharing this because I wasn't even made aware of it when I got into shooting. Shooting and eating after without even washing hands was no big deal. Most of you are aware that the bullets are generally made of lead, often jacketed in copper. What you may not know is that the primers are almost always made with lead, which seems to be the greatest cause of the exposure to the shooter.
My synoposis is that at a minimum, wash your hands thoroughly after shooting. Ideally, change clothes as well. Risk is likely highest in indoor ranges.
This is not at all to discourage shooting. I'm quite fond of firearms in general. This is more to raise awareness of the risks.
