I was under the impression that the rifled slug was for a smooth bore barrel but can you use them with a rifled barrel?
You can use a rifled slug in either a smooth bore, choked bore (preferrably Modified or more open choke) or a rifled barrel. It will definatley fly alot further and much more accurately in a rifled barrel than in a choked or smooth bore barrel, that's the whole idea.
rifled slugs were originally designed for use in smoothbore barrels. since there was no rifling in the bbl, they put it on the slug to get spin and stabilize the slug and increase accuracy. will they fire from a gun with a rifled bbl yes but weren't really designed for that. as for accuracy who knows, I'm sure each gun and load will give different degrees of accuracy. slugs inside plastic sabots are the order of the day for rifled shotgun barrels today, similar to muzzleloaders. some claim 200 yard accuracy and much faster velocities but can cost 3$ or more each. if you can find a rifled slug/smoothbore combo that gives decent accuracy 50-75 yds you could save some $ and wt as the rifled bbls tend to be thicker and heavier.
I have always used the cheap remington green slugs they have never failed me, I have killed deer out at 200yds+ with them.over all I have killed probly 30+ deer with them (Smooth bore). I switched to brenike or however you spell it($10 a box) and lost a deer that I hit @ 20 yds I literally watched the slug hit it in the front shoulder. The other more expensive slugs seem to be made out of a softer lead witch mushrooms alot easier instead of punching a hole thru. Federals aren't bad other in a pinch, grab 4 or 5 different kinds and see what your gun likes they all shoot different my browning A-5 love those green remingtons and so does my wallet.
