Just skimmed it (about to go to bed), but I'm not impressed:<p>For starters, as others have noted, the danger is from the lead styphnate in primers when used in indoor ranges. They ought to have made that clear ... especially since there's an obvious solution which is good for ranges (we don't entirely trust lead free primers yet, but unless one causes a squib misfire that lodges a bullet in the barrel, it's not a serious problem).<p>They invoke the eeeeevil NRA ... which is the organization of gun <i>owners</i>. Not a word about the National Shooting Sports Foundation (NSSF), the organization for the gun <i>industry</i>, including ranges.<p>Don't know if they went into it for real, but this danger has been generally recognized for as long as 3 decades. The NRA has certainly been telling its members about it. Just like we're told not to eat or smoke while reloading. Of course, there's more than one compelling reason to not smoke while reloading ^_^.
Anyone know in what form lead occurs in the residue/vapour at gun ranges?<p>Is it all native Pb, or are other more soluble compounds formed during firing?
