The environmental concerns with lead have been recognized for decades concerning wildlife (especially waterfowl and condors). My experience is the biggest problem
is improperly disposed lead/acid batteries, and I can't speak to use of lead in buildings. Lead exposure within a manufacturing plant is very controllable using basic well espablished requirements (proper gloves, respirators, showers before they leave, shoes
and uniforms never leave the building except for the laundry service).
Jim - gun racks went of habit years ago due to thieves, not all who drive trucks are rednecks (with or without 4 wheel drive), guarantee there are not that many
pickups out there at $80,000 and most are sold with 4WD even if you don't need it.
The hard part of lead is the lack of knowledge and ignoring of proven science - proof being people still smoke cigarettes.
You all play nice! We all want the same thing - safety!

Yes, steel shot and even titanium/bismuth alloys have been available for a long time, but I can buy all the lead shot 12 gauge loads I want. And in my art world,
the equivalent of the guy casting his own bullets is the idiots casting their own lead-type for letter press printing. And some of this is going on at universities!!
Did you know that art departments at many universities are graduating students who have demonstrated their proficiency at printing and binding their own wee books
with their own type and making their own paper. Now these are graduates with serious job placement issues.

Monona,
I have been handling unpainted sheet lead and bricks for 40 years while fabricating radiation shielding on a variety DOE, DOD, EPA, USNRC and civilian radiological
and environmental projects. The only PPE required by the government was leather gloves and of course steel toe boots.
By the way, Those pickup trucks are $80,000 and use diesel fuel which is more expensive than gasoline. They are invariably 4 wheel drive although they have never
been used off road by the pretend rednecks who drive them. I even saw one at the train station parking lot with an umbrella inn the gun rack.
Steel shot, as opposed to lead, has been used for hunting water fowl for many years. The lead bullets along with the expended brass are regularly collected and recycled
by shooting range operators.
If that (pickup truck driver-hunter-shooter-loader) is making his own lead bullets he is exposed to lead by handling and melting the lead to mold the bullets.
As a former Soldier I can attest to the fact that we introduced lead bullets by the billions to environment worldwide during training and combat.
Now that I perform environmental soil remediation (on DOD sites) I am making a bit of money while correcting these issues.
I always look forward to your Emails they are both entertaining and informative.
