I'm sure they would be regulated for lead ammunition. Since you have posted tons of links to junk science supporting bans on lead ammunition, I don't think you would want a gun that would send lead slugs into the environment.

That is my opinion, which you requested. Hopefully, nobody else will offer anything else to a staunch proponent of banning lead ammunition, thus making shooting much more expensive.

A true sign of mental illness is any gun owner who would vote for an Anti-Gunner like Joe Biden.
