When I was a kid, I used to shoot my wrist rocket with a load of 6 or 8 .177 caliber copper coated BB's. Everyone used to warn me I'd end up with several BB's stuck in my hand and have to visit with a surgeon to have them removed. I probably made 100+ shots like that and never had a problem. I know it's not a good idea, but will probably try it again to see if it still works for me. BTW I got my nickname from a friend later in life, due to the way I go about building something all at once instead of planning it out in steps and working through it in an orderly fashion. I have also bolstered that nickname with some products made by Mossberg and sons.
