I really want to see elimination of lead (projectiles, lead styphnate primers, etc.) in firearms next.

When I go to the range, every once in a while, I'll see one of the older marksmen who's there with his squirrel hunting rifle, chambered in .22 LR. I've noticed that he seems to have a tremor in his hands when he's loading his magazines. Essential tremor is linked to lead exposure [0]

Most .22 LR projectiles are either just lead or have a copper "wash" over the lead, not a proper jacket like you see on other rounds.

I wonder, if you shoot those loads for long enough, and breathe in enough gunsmoke, do you get that problem?

As for the proof being in our hair... well, not mine. Chrome dome over here XD

Why would lead be in the gunsmoke? Everything leaded should be coming out the business end of the firearm, and it should be coming out with some gusto.

The base of the bullet is lead (with jacketed pistol rounds, that's often true even if it's a "full metal jacket" and some brands are trying to draw a distinction there with "total metal jacket" branding) and it's exposed to the explosion when the round fires. There's some vaporized lead, most if it will move downrange and some of it won't. Airborne lead is potentially more of a problem at an indoor range.

Copper, polymer-coated, or total metal jacket rounds will also result in less lead on the firearm, I'd think, and less on the user's hands. One old guy I know who had lead poisoning at one time believes the real risk is getting the lead on one's hands and then handling a cigarette.
