You’d have to shoot thousands of rounds in an unventilated room to get even close to one day of leaded gasoline exposure
I figured copper jackets would greatly reduce lead exposure, which is all I used when I used to shoot.
Leaded gas wasn't fully stopped until 1996. Still in some aviation used (piston plane engines).
But yes I wonder about shooting ranges too. I think a couple times a year at an indoor range isn't insignificant.
You're half right, they're are brain damaged.
But bullets?
I don't know man. Seems unlikely. Leaded fuel and lead paint tho..?
#Lead Exposure in Last Century Shrank IQ Scores of Half of Americans

A new study calculates that exposure to car exhaust from leaded gas during childhood stole a collective 824 million IQ points from more than 170 million Americans alive today, about half the population of the United States.
