I've done it 3 times this year (seems to be a popular number), and believe me when I say I don't like it. If it meant I was a great shot, I'd love it, but all it means is that I was lucky (unlucky actually). If I could call the shot and do it everytime, then it would show skill, but heck one is bound to hit where another one does, when you shoot thousands of shots. It's just bad luck and costly too.
