I run Winchester Super X rifled slugs through my Remington 1100 if I'm feeling cheap that year and Hornady SST sabots if I'm hunting an area where I may encounter a longer shot.Average about the same as you with the Super X at 75 yards and get about a 2" group at 100 yards with the SST's..Trying out the .44mag this year so the girlfriend is using the 1100
