I'm no expert, but from what i understand is that rifled slugs aren't really "rifled" in that they don't spin the slug any,.
From different tests I've seen there is no problem shooting rifled slugs through a rifled barrel and accuracy will probably be better than the same slugs fired through a smooth bore. In one test the rifled slugs weren't far behind sabots in accuracy at 1/4 the cost. For 75yards or less I find it hard to justify the price of sabot slugs.
