I haven't honestly researched this topic a whole lot, and frankly this topic won't keep me from going to the indoor gun ranges often, but I want to ask all of you here what your opinions on this matter is? Is there any kind of long term health risk asscoiated with air pollution inside gun ranges? I mean like the gun smoke, bullet fragmentation, possible lead in the air, ect. I got the idea for this thread from what I read about frangible bullets. A website deemed frangiblebullets.com mentioned lead floating in the air, and promoted frangible bullets by mentioning that these bullets are lead free, ect.
