I think if your buddies are regulars on the sporting clays range, ask them to keep on the watch for any club member or aqaintance guns that become available, and consider them on an individual basis. I would not imagine or hope that it would have cross usefulness in the field, except maybe for blind hunting.

Also, it was a great thing that you could find shells, but that might not be regularly so. Maybe, build your stash when you can and not wait for the gun if you figure it's happening anyway. Maybe, shoot your field guns for now, and possibly a better value will come with some patience, good luck with it.
