I have shot several deer with the regular old federal or winchester "foster" type slugs with a rifled barrel. They were plenty accurate at 50-60 yards, the accuracy wasn't that great at 100 yards though. The only problem I had was they leaded up the rifling in the barrel so I had to clean it well. Don't shoot brenneke K.O's thru it, they have little wings on them to make them spin in a smooth barrel. They made a "whizzing" sound and flew every which way but where I wanted them. I am trying to come up with the best sabot slug for my combination with maximum accuracy and distance in mind. I hear of people shooting out to 200 yards now. I'd be comfortable with 125-150 with a solid rest at a standing deer when sighted in.
