Most lead contamination you get is from shooting in poorly-vented indoor ranges. But, you can also get it from shooting on an outdoor range and doing anything with lead bullets indoors- i.e. casting, reloading , etc. As to the actual risk involved in any of those activities, I wouldn't hazard a guess.
Attached is a link to one instructor's views on the subject:

Due to OSHA regs and such, I have adopted several measures when I run a range. I use an indoor range only if it's a extreme necessity. But even at my outdoor ranges, I do the following:
- I have warm water and soap and paper towels available for the shooters. Wash your hands and face and any other exposed skin.
- I have a bucket and brush so they can wash the bottom of their footwear before they climb in their car (or worse, the cruiser they drove to the range that I drive while at work).
- I highly suggest they bring a change of outer clothes and change before they get in their car. Likewise, I strongly urge them to bring an extra pair of footwear to change into prior to climbing into the family mini-van.
- I tell them to wash the clothes they wore separate from any other clothes. That's the same thing I tell them after any kind of exposure to OC spray.
It may be overkill, but we have at least two firearms instructors in the state (that I know of) who have a level over 60 mcg/dl and have either been put out on disability or Worker's Comp. I know of three others that aren't firearms instructors anymore due to the levels in their system. I will grant you that all of them were using indoor ranges most of the time, but once again, given OSHA and the various liability issues involved, a person running a range should be careful.
I know for a fact my levels went up. After learning about this issue during my first instructor certification course, I went to the doctor and had my blood tested. I was down in the low teens. Shortly thereafter, I embraced the whole firearms instructor concept and started shooting several times a week. After all, as an instructor, one MUST be the greatest shot in the world!
Not true, but ....
I did most of my shooting at several indoor ranges and found out a mere 2 years later that my levels had jumped up to the high 30's. I stopped going to those ranges.
My rather unscientific rules are:
- If you are shooting, and you get a kind of sweet taste in your mouth- you're ingesting lead. (Others may poo-poo that, but hey, it's my rule-of-thumb... and I'm sticking to it.)
- If you aren't washing after shooting and sitting down and eating a burger, you're probably ingesting lead.
- If you handle things that you put in your mouth during the period you're shooting, you are probably transferring lead to your mouth. I use cigarettes, cigars, and "dip" as an example. I am a smoker. After finishing a relay, I step off the line and shove a cigarette in my mouth, I am probably putting lead in there also. Of course, the cigarettes are probably going to kill me before the lead does, but... it doesn't mean I'm still not compounding the problem by eating lead.
I'll now end this and post another reply that should counter everything I just said.
