They would take a considerable fraction of a second to reach the 55 yards range, and pellets would drop a foot by the force of gravity in ¼ second, therefore some of them would not pass through the 4 feet opening. On this assumption, instead of the 50 yards columns of shot being of the lengths stated, they must be very much longer, with a continuous dropping of the weaker shot all up the range.
