Was at the Sportsman's Exposition in San Mateo today and picked up a flyer at the Dept of Fish & Game. There is now a sizeable hunk of central to southern California that prohibits the use of bullets containing lead while hunting including .22 rimfire even. The way the law defines it, even airguns are included. No lead cores even in jacketted bullets.
You can still target shoot using lead in areas where they will allow that but during fire season, they prohibit even that in some areas (Hunter-Ligget Military Reservation for one).
The thing is is that lead fragments from wounded animals that die later and are scavenged by condors contribute to the ingestion of the lead by the condors & so the condors die of lead poisoning they are saying. So a paper target is still OK.
The good news is that the guy I went to the show with is a guy who works for a local dealership and is going to save me a couple of buckets of wheel weights.
