I have shot a few coyotes with stingers and they all died pretty quick. They usually would drop down at the shot, stumble a few yards and die. They were all shot at about 10 yards way. I was shooting them to keep them out of the barn area of the ranch I worked on. I have taught my wife to use the 10/22 for SD. When we shoot it, she knows to shoot in three round burst. She can keep all three in a fist sized pattern at 10 to 15 yards. This is better for her than the shotgun she refused to shoot. I am not going to volunteer to see how lethal this theory is.
Credo Quia Absurdum!
