When I was a kid I used the CEEbEE long a lot but it was out of a rifle, they where very quite and accurate and surprisingly powerful.
One time I saw a goose out in a field, it was well over 200 yards and I never thought I would hit it let alone kill it.I added a lot of Kentucky windage to the rifle and squeezed the trigger, well a few seconds latter I saw the goose flap it's wings and take a step and fall over dead
When I went to get the goose I got caught and talk about a scared kid, it turned out to be a domesticated goose and the owner ate it for dinner and never did tell my parents.
