A few years back I had to "discretely" take out a mangy coyote with a large growth on it's right hip in a N Texas city. Used a 22LR in a rifle. Shot it from about 60 yards, head shot, as it was looking straight at me. When my partner walked up to it the thing jumped up and faced him. He had to finish it with a 9mm. (There went "discrete") As it turned out my 22 shot had hit just above the eyes in the center of the head, plowed a furrow through the hair and ricocheted off into the bank beyond.
