Agreed. I scotch doubled two green heads while walking the marshes of Maine this weekend. I was u loaded, near the road heading back to the truck. Two green heads flew out of a 1' wide draw and flew off. I was able to load and shoot and hit both with a single shell of BOSS #5 bismuth at about 40-45 yards and take them both down. I didn't even know I hit the second, too focused on the first, but my partner saw the second drop as well. I'm a believer in the bismuth now
