I can see these kinds of laws continuing on and on forever or at least up until the point that the SCOTUS provides some detailed direction that you have a right to bear arms outside of your house and that in order to be able to reasonably employ them in self defense they must be allowed to be loaded..
. . . And that if they are in common use for traditionally lawful purposes or suitable for a would-be militia, then they cannot be banned, no matter how scary they look.
