I have one of the first guns delivered. All of those 'launch guns' were 20's. It has been shot quite a lot since then, almost exclusively at dove and pigeons. I've taken it out of the country several times for that purpose and also used it on perdiz, but on a much smaller number of rounds. It is a delightful field gun for that purpose and has never given me the first issue. It is not a clay target gun if one is going to shoot it pre-mounted, but it was never intended to be. I remain very fond of it for 'take all comers' dove shooting.
