That is so awesome, Renegade! I would have thought the ranges would have decreased becase air escapes where the clip is, correct?
No, it doesn't decrease range as much as you'd think. The only air that escapes is the air that gets inbetween the brass and the pvc, which when you think about it isn't much. It works just like a breech loader.
I think this is a pretty neat concept, although its not really something you might use often, it's a creative idea and its something new and cool to try out. Nice job.
