A standard factory full choke would probably not reach the tree rats in the 140'+ tall pines in my back yard, especially if you were not standing directly under the tree and aiming straight up. IMO I'd go find a turkey full etc...and run some pattern board tests to see what ammo holds the best pattern's in your gun out until at what distance the pattern falls apart. BTDT out to 50-55 yards was my gun's max and had some real surprises on what ammo to shoot. We were pass shooting geese at Lake Texoma in those days.
