Worst I have seen is...
this guy slid feet first got stabbed in the ass by a stob. BIG puncture wound in the right cheek. He had to be carried away on a stretcher. Really bloody. My worst was when I broke the end of my finger by sticking it in my impulse's barrel. Walking around, I stumbled and hit the trigger. FA, at least five balls broke on my finger, shattering the end phalange. Needless to say, the stock board went back in and the barrel stays off when I am working on it.
