World's Largest Shotgun.

The Punt Gun.

The Punt Gun is an extremely large shotgun used in the 19th & 20th centuries for shooting large numbers of waterfowl for commercial harvesting operations. Punt guns were usually custom designed and so varied widely, but could have a bore diameters exceeding 2 inches and fire a pound of shot at a time. A single shot could kill over 50 waterfowl resting on the waters surface. They were to big to hold and the recoil so great that they were mounted directly on the punts (boats) used for hunting, hence their name. Hunters would maneuver their punts quietly into line of range of the flock using poles to avoid startling the flock. Generally the gun was fixed to the punt; thus the hunter would maneuver the entire boat in order to aim the gun.

This site will show some pictures of the punt gun and the very last video on the page will show the punt gun being fired.
