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.

		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.
