Well, I have a really good one. Not about slinging, but maybe better.
It seems that one day when I lived way out in the country I was on my back porch with my .22 rimfire target rifle. I was, of course, shooting targets that I had set up way out in the back. Well, I see this shadow on the ground moving very fast. It came from behind me and was moving straight ahead of me. I looked up and saw a very large Turkey Vulture (wingspan in the 8 foot range, and very heavy bird.)
Birds have incredible hearing. We have a bird here called the American Robin. It finds worms on the ground by hearing where they are. Most birds have this kind of keen hearing. I wondered to myself, "Self, I wonder if that vulture could hear a bullet whizzing passed it?"
By this time, the vulture was about 50 meters away and at least that high off the ground. I pulled my rifle up and got the vulture in the scope, crosshairs right on the bird. I lead out in front of the vulture about 3 or 4 meters and fired a shot.
Of course, you know what happened right? POOF! Feathers flew in the air as the bullet grazed the bird's belly. It wobbled in the air wildly for a few seconds the flew off unhurt.
It is illegal to kill a bird of prey in my state and I fervently abide by the hunting laws. Boy, did I ever feel bad. I told my wife and she said, "I can hear you explain this one to the game warden, 'Honest, warden, I was not trying to shoot the bird; I just aimed at it and pulled the tirgger.'"
She was right on. I did something stupid and it almost ended very badly.

P.S. Before anyone flames me for hunting or such, be warned, it would be an unwise thing to do.
