Actually, I have a rifled choke tube in my 20” iron sighted Rem 870. It will shoot slugs in the black at 90 yds. and still pattern buckshot well at 30 - 35 yds. I keep it handy at home for that reason.
If you were shooting a fully rifled slug gun I suppose that might give the shot cup a pretty good spin though. Bet that was ammusing to observe.
I had swapped a fully-rifled slug barrel onto my shotgun. My instructor joked that I had discovered a novel way to deal with a hostage situation: aim at the hostage and it would get everybody around him.
