I use Hornady's 2000fps sabot slugs out of my mossberg 500 slugster w/ a rifled barrel. I bought a few brands and tried them all. The rest wouldn't hold a 10 inch group at 100 yds (federal, remington, winchester) but the hornady sabot made about a 1-2 in. group at 100. That's good enough for me, plus they have plenty of power to make the rare long shot. Last year I dropped a nice 7pt buck in his tracks at 150 yds. Only had to aim about 3 inches high and he just flopped. Whats important though is experimentation, different rifled barrels like different rounds. I am sure the hornady won't work in other barrels like it does mine and vis versa.
