Nomercy; The first 2 whitetails I every took were with my 12ga. side by side. The gun shoots dead on at +/-40 yds. After that the right side travels to the left and the left side goes to the right. One of the deer I shot was about 90yds and broadside and walking from left to right. Aiming for the heart/lung area, the first shot(right side barrel) hit the deer in the back hip. The second shot (left side) hit the deer in the neck. So at about 90yds the spread was almost the length of the deer.
