Heck we've all done some silly stuff learning what we know, We've managed to survive and if we can pass on some of what we have learned the "hard way" it might save someone else. I've personally shot a double charge second charge didn't go off until it cleared the barrel, was really strange trying to figure out why there was 2 holes in the target. Now here is a question just because I don't know and it might work. What about the CO2 setup that is made to screw into a nipple thread and see if it pops out that way. I'm not sure it would work on a double charge but it's food for thought. And YEP he's welcome to set up in the stall next to me, maybe I can help him learn the sport.
