There is nothing wrong with a smooth bore and foster slugs. I shoot them and they do a great job on deer out to 75 yards or so. If you are going to shoot long distances get a rifled barrel and shoot the sabot slugs. IMHO there are a lot of people shooting the sabots out of rifled barrels that don't need to as they are not shooting the long distances. In addition the rifled barrels are a lot heavier than the smooth bore barrels.
