I feel that what you shoot them is a hugely deciding factor. I like to hit 'em out to about 140 yards with a 1-3/8 oz. 12 gauge Brenekke Gold Magnum, with shot placement either directly in the old boiler room or above it to the spine and forward to about 6-8 inches in front of the shoulder. I ain't had any problems with leg movement after the shot, just leg buckling!
