What are your thoughts on the Thunder 100's to be used in place of a popper gun for picnic and licensed hunt tests? A club member brought one of these to our picnic and from a safety standpoint, I really liked it. The initial purchase is obviously much more expensive than popper guns and poppers, but if they are reliable long term, it would not take too long to become more economical than popper guns and poppers. Do any of you have one? How do you like it? What are the pro's and con's you see or think? Thanks
