You must have given him a severe concussion he couldn't survive from Dave. Good shot on that small target! Could it be the velocity dropped on the 850 from the cold weather if the shot was outdoors? I missed a crow 1 time and watched the pellet graze its feathers right below its chest at 25 yards when I was aiming dead center and had the 850 zeroed at 25yds. I went back inside and took 1 shot through the Chrony and it read only 550fps, >100fps slower than when I shoot it at room temp. from inside the house.
