When I was about 16, I took the Stevens Semi-Auto .22 rifle hunting during the winter. A buddy and I walked down the long camp road and I saw a white hare about 25 yards away, sitting motionless, but headed toward the right. I shot it through the lungs, but it didn't fall over, so I shot it again. Same result.
I emptied the gun on the rabbit and apparently hit nearly the same place, because I could see right through the critter! It was dead, but apparently didn't know it. I reloaded and shot it through the head and it finally fell over.
Never shot a group on a critter before or since. LOL
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
