It is legal to hunt in North Carolina as of last fall as well. We have, as of the last election cycle, had our first Republican House, Senate and Governor in over 100 years. One of their first agenda issues was the use of cans for hunting.
It still take forever it seems to get one through the federal system.
I have a 30 cal rifle and a .40 S&W (used for my 9s as well) pistol in my gun safe. I have a Mystic 5.56/9mm can and a .22 can in jail. I get to look at them occasionally at my dealer

Federally, they are still considered a "weapon of mass destruction". Makes little sense.
