Some of you may be aware of the potential for high lead levels in your blood due to indoor shooting. I am going through that right now. Indoor shooting in moderation is ok but please make sure there is always adequate ventalation otherwise just leave. Don't shoot indoors with lead or around other people that shoot lead. I'm sure this is no revelation to people shooting for years but for me it's an awakening. After talking to some people and doing some research on the web it appears that taking in extra Vitamin C is a way to address the problem. > 1000 mg per day.
