I struggled with slug guns for years. I finally bought a Benelli slug barrel for my SBE. Best money I ever spent. Tried several loads but when I put the Winchester Supreme through it...bingo. My first slug buck with the new rig was 100 yards away. Dead on. I have no worries out to 150 yards. This combo is very accurate. FYI: I have a Nikon 3x9x40 camo (to match my SBE) mounted on it.
Let us forgive our brother who speaks bad of our name behind our back.....bury the hatchet and sit around the campfire as if we all had guns!
