If you know how to position yourself hunting over Beagle hounds then 10-20 yard shots are rare. Most every rabbit I have shot off my dogs has been within 10 yards. Cottontails tend to do a circle and are fairly easy to set up on. That little judge with some 5 or 6 should be fine. I've got a little Beretta OU .410 that I tend to use more than any of my other shotguns for rabbit.
