From another fourm on the topic of lead;
Lead levels in the human body, when measured via blood test are expressed as "micrograms per deciliter". That said, here are some factors to consider:
Most of the issue with lead ingestion comes from shooting on INDOOR RANGES. The ones outdoors have enough ventilation and natural "cleaning" factors to reduce the lead ingestion levels pretty easily.
Lead ingestion by shooters comes from 4 major sources, not necessarily listed in order of significance:
1. molten airborne lead particles generated during firing, melting off the back of lead bullets, and inhaled
2. particulate lead absorbed when touching/handling lead bullets
3. lead primer byproducts inhaled as a result of shooting
4. molten lead particles inhaled during casting lead bullets
Most of us don't cast our own bullets, so we can ignore #4 above as a source of lead ingestion. However...source #3 above is by FAR the BIGGEST CONTRIBUTOR to lead ingestion by shooters. (It's something like 10 times greater than the next highest source!!)
The reason here is that, most "non-corrosive" primers contain lead styphnate or something similar. When lead primers ignite, the chemical reaction creates a lead salt that is airborne, and worse yet, it hydroscopic, like all salts. It picks up moisture easily.
Guess what's in your throat and lungs? Lots of moisture, waiting for the lead salt to combine with it. Instant absorbtion.
The solution---RIGOROUS cleanliness on the range, and care when shooting indoors:
1. Don't smoke, eat, or drink on the range. You are ingesting just that much more lead in doing so.
2. Don't shoot on an indoor range that does not ventilate by pulling combustion products AWAY from the shooting line. If you MUST shoot on a range with poor ventilation (Lord knows why), use an approved mask.
3. DON'T SWEEP with a broom on an indoor range. The floor is COVERED in lead salts, and brooming puts them back in the air.
4. Once you are done shooting on an indoor range, wash your hands immediately. If you can take a shower and change clothes ASAP, all the better.
5. Lastly, DON'T go to bed after shooting indoors until you take a shower and wash your hair. You hair traps lots of lead particles that will transfer to your pillow, and then to your mouth/nose while sleeping.
People I know who have followed the above rules can sucessfully shoot indoors A LOT (like IPSC practice multiple times per week) without having excessive lead levels.

If you don't "Buy it" well, who am I to argue with the way you treat your body? As for reloading, I've been reloading since 1986, since then I've had 3 bad bouts of elevated blood lead levels. In each case the Base Medical Officer restricted(read that disallowed) my shooting for a 6 month period while the blood lead level returned to normal. If you are going to wear a mask while shooting go to a certified safety supply store and purchase a mask that is rated as effective in stopping lead airborne contaminent. Most lead on indoor ranges is made airborne by your feet as you walk down the indoor range. While I was in the service, part of retaining my RSO qualification for indoor ranges was that I had to get a blood test every 6 months.
Elevated blood lead levels are nothing to f*ck around with they can cause serious damage to your body. Loss of co-ordination, loss of memory, mood swings, etc. It can really screw relationships up badly. Since I retired I only shoot outdoors which helps minimize airborne lead contaminent. A PMed tech I used to shoot with also let me in on a secret, during the reloading process on a single stage press, you can handle a single round 5-6 times. Your skin absorbs a lot of lead this way. When reloading I now wear latex surgical gloves and since they are cheap, use them in bulk. This way the only time my hands actually touch lead is when I load and fire the firearm. I have shot IPSC and Cowboy action and I am a high volume shooter!
