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.

[Eagles6]

Yes. Used for shooting rifled slugs for big game, generally used in states or areas that disallow rifles.

[NFHale]

There are rifled slug barrels for shotguns.

[QualityMan]

Yes, I own one. Fits my 870. Made by Hastings.

[Paladin2]

There are saboted bullets in shotgun shells where the plastic sabot spins the bullet up using the barrel rifling.

All sorts of bullets available.

Yes, Virginia, they do. Of course, to be technical, a shotgun is no longer a shotgun once a rifled barrel is placed on it. If you get my drift.

Go to Remington.com and feast yer eyes on the deer barrels and such.

Yes, for shooting the plastic sabots that contain a slug smaller than 12 gauge. I prefer rifled slugs that have grooves on the slug and should be fired in a smooth bore improved cylinder. I have a 20” Remington barrel for my 870 that is smooth bore with rifle sights and uses screw in chokes, the improved cylinder for rifled slugs, a full choke for turkey hunting and a rifled choke if I wanted to use sabots. The Improved cylinder is also best for 00 buck.

There are rifled handguns that shoot shotgun shells. No legal smoothbore ones, though, except NFA weapons.
