Oh it's much worse than just that , the " button law" as regards magazines on the " assault rifles" , a lot of NON CAl handguns because of the absolutely ridiculous drop test , no .50 bmg chambered rifle ( not that I'd want one but show me a crime every commited with one in the States) , and then of course we have the "condor Zones" ( no lead zones) and the states and feds jumping outa the bushes at duck and goose hunters to wave the magic wand over your shotshells and make sure that they're steel shot and you don't have any more allowed ( fined by the shell by the way).
As has been pointed out several of the southern states and certain others are still sort of open , but the FEds have raided gun shows all over the country in locales where that goes on in an effort to close said loophole , some NC ones got raided due to impetus from the Northern cities , too many " straw buyers" taking 'em back to NYC , DC , Jersey etc.
And they've raided in Texas and Louisiana too. And if you've noticed certain firearms are at an extreme premium and the price of ammo and components is wwwaayyyyy up , you're not getting propellant for 10 bucks a lb anymore and slugs have gone up enough that I'm back to casting and swaging my own.
