you can shoot rifled slugs thru any shotgun barrel. I think it actually tells you on the slugs that rifled slugs will shoot best thru either a mod choke or a rifled choke tube. but Im relatively certain that rifled slugs can be fired thru any smoothbore of matching caliber.
In the back of my mind I'm thinking you're not supposed to shoot them thru a full choke....I don't know though if that's an absolute no-no or if its just not ideal for performance.
I have fired many rifled slugs thru a 12ga mod choke barrel. at short distance....just point and shoot...aim down the barrel. works better than you'd imagine.
