I believe that a 12 gauge shotgun is .71 cal. I don't know about a 10 gauge, but it is certainly larger.

bigger than .5 inches, but they are shotguns.

If I remember correctly, one of the reasons that BAFT said they had to invade the Branch Dividians in Texas was that they had a Brittish Boyes anti-tank rifle that was technically a destructive device, as its bore exceeded .5 inches.

I thought I remembers that the limits were .5 inch and .6 inch with some confusion.

I looked up the People's Republic of Kalifornia's definitions of Destructive Device out of curiosity.

More restrictive California definition of destructive device

While this makes no sense, it is the law.
