yup, thats how it all got started with shotguns. Rifled barrels followed a long time later. You won't have the accuracy of a good rifled barrel but for short range it'll do. Try a couple of different brands of slugs and see which one shoots best. I would shoot them at 25 yds to see where they print then at 50 yds. Try shooting at a 3'X3' target with a 5" bullseye and of course a good backstop. Those slugs can move around quite a bit from some barrels. Good luck!
