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

I completely agree. I do everything I can to avoid leaded ammunition. I do not want lead touching the meat I harvest. It can be really tricky to find lead-free ammo of certain sizes. I mostly use waterfowl ammo for upland bird and rabbit - and it works fine. But even ordering ammo online it is quite hard to get .270 solid copper. And in a store? Forget about it

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.

Because the heat and pressure from the propellant and rifling vaporizes or rubs off some of that lead. A very small percentage, granted, but still.

Particularly for unjacketed bullets like 22LR. Even jacketed bullets tend to not be jacketed at the base.

>>1970-0+x8
The material that burns in primers is often lead styphnate. This burns and sends lead particles throughout the air.

With rounds that aren't well jacketed like those 22s that are just bare lead, you also get some of the round scraping in the barrels that comes off as dust.

There's tons of lead in the air at shooting ranges.

Are you proposing that the base of the bullet which is exposed to the burning propellant magically remains at room temperature, and none of the lead in the base of the bullet is vaporized? What about the process of forcing the projectile into the barrel's spiral grooves at very high speed, leaving grooves in the side of the bullet. Where do you suppose that displaced and/or vaporized material ends up? What about the lead styphante that is combusted in the primer? I am not aware of any firearm that has a muzzle filter that removes primer residue from the combusted gunsmoke.

I am directly questioning whether the .22LR bullet creates more lead vapor than any other round as per OP statement.

>>1970-0+x8
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.

There was a big case in Berlin where policemen got sick after shooting at a range with insufficient ventilation.

I haven't measured this but all the ingredients are there: they're unjacketed or copper washed, and they are made from soft lead rather than a hard-cast alloy. You can get a polymer-coated or pure copper round but that's pretty unusual since it goes against the cheap plinking purpose most people are using the .22 for.
