Since we're on the topic of ricohets, I've had them even shooting golf balls. Buddy threw a golf ball out in front of me while shooting. I had his PTR-91 7.62mm (H&K G3 clone) and proceeded to shoot the ball three times, bouncing it down the range. Third shot, jacket separated from the core and ricocheted back and smacked him in the neck. Luckily, nothing happened to him though.
