I shoot Lightfields out of my 20 gauge H&R Ultra Slug. I shoot 2" high one hole groups at 50 yards, dead on at 100 yards and about 2.5" low and 3.5"groups at 125 Yards. I haven't shot it any futher than that, most of my shots will be inside of 100 yards. Before this gun I used a Wincherster Ranger auto with a rifled choke tube and Remington Copper Solids and it was a sniper out to 75 yards. Then after about 10 years it I could not get it to group, think the tube was shot out.
