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. If your going to shoot in your house learn how to wet mop up lead contaminent before you make your whole family sick. Kids are affected far easier than adults
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!
