For smoothbore I always had the best accuracy from Winchester rifled slugs until Federal came out with their Tru-Ball rifled slugs. Those were pretty impressive for consistency.
I bought a fully rifled 870 and fount the best consistently from Lightfield Hybrid sabots. Nice consistet groups out to 100 yards. I found that every other sabot load would stack them in there but constantly throw a flyer on a 5 shot group.
I killed 1 deer with that combo on the first hunt. NY made it legal the very next season to use rifles, and I haven’t shot it since!
And yes, you can shoot rifled slugs from a rifled barrel just fine if you’re not concerned with wringing as much potential as possible from your shotgun. Outside of extreme circumstances, that just seems wrong! Lol.
Good luck with your new shotgun sir.
