I had this happen to me when I was a Kid shooting Pachinko Balls with my wrist rocket and hitting a rock, fortunately it missed me, came really close to hitting me in the head, that's when I stopped using steel Pachinko balls and went to lead musket balls....... Ha Ha, brought back some memories, we use to shoot trap with our Wrist Rockets, We made special pockets to hold shotgun shot and it worked great, even took down a Pheasant, but mostly Dove, Quail and Lizards.....
Here he is later after the video
Know your taget and what lies beyond, backstops are important.
Thinking about getting my ex-wife one of those
Even though the video was fake, it sure reminded me of the close calls when I was a Kid goofing around with my wrist rocket.....
