No, I've never shot it. The barrel is frozen on it, and while I could get a wrench made up to take it off, I'd hate to break anything on it.
I have shot an original percussion screw-barrel that I own. At about 10 feet, the ball bounced off 1/2" plywood and dropped onto the toe of my boot. That was enough of that...well, after a few more shots at a haybale, actually...no, I did shoot it again at least one other time (just stupid, I guess :shake: ), but never again at anything like plywood.
I have seen someone get a bullet back in the family jewels from a bowling pin. Didn't penetrate his jeans, but he went down. I'd rather not have that (or an eye, even with glasses) happen to me. If you want to shoot one, be very careful. That ball is travelling very slowly.
