Yes Brennekke says all of their "Foster" Slugs can be shot out of a rifled or smooth bore bbl.
I am going to try some cheapo brenekke K.O.'s in my rifled barrel when ever I get to bench rest it. and A box of Hornady 300g SST Sabots. Even the Hornady's say the drop at 200 yards is 10" on the BC. 50-100 yards was 1-2" high and 150 yards was 2" drop. So if you sight in with sabots at 100 yards you should be able to get a group with in 3-4" from a bench.
