What about a rifled shotgun barrel?
Do those exist? A shotgun is a smoothbore barreled longarm. I don't think I've ever seen a rifled shotgun barrel.
A smooth bore is classified as a "shotgun" regardless of length, that is why all handgun barrels (aside from black powder, which are exempted) are all rifled. A smooth-bore pistol barrel is technically an illegal short-barreled shotgun.
A shotgun barrel is almost never rifled because a rifled barrel will spin the load of shot, and the centrifugal force will cause the shot pattern to go into a donut shape.
People who have tried shooting pigeons with .22 shot pellets will drive themselves crazy, because if the bird is at the point of aim, he will likely emerge unscathed.
Slugs may have rifled sabots which would cause the slug to spin down the barrel, but the barrel itself is smooth.
So many why’s and if’s in ATF enforcement. There is very little rational thought to the laws or enforcement.
Why is a smoothbore .410 with a 15” barrel illegal, while the Taurus Judge is legal?
Why do I need a class 3 to have a “concealable short-barrelled shotgun” if I already have a concealed weapons permit?
If pistols are more dangerous than rifles (which is inferred from how they are treated) then why is illegal to turn a pistol into a rifle?
If pistols are legal, why is it illegal to turn a rifle into a pistol?
Why is it 16” for rifles and 18” for shotguns?
It is the arbitrary and capricious LAW. Ask some who worked for FDR in 1934. He also wanted to ban HANDGUNS!
ATF BS.
Made up rules which do NOTHING to stop crime.
