Finally got a pic of the third one this spring. I was at a double gun shoot and the rancher said if I called one in to kill it as it was harassing his cows. I didn't have any rifle ammo with me but found 3 BB hand loads and called it in to 44 yards.
2 1/2" 16ga/16ga/9.3x72R Killed it with and ounce of BB's
