Called the “Punt Gun” this firearm of unusual size could discharge over a pound of shot at a time, and dispatch upwards of fifty waterfowl in a single go. A punt gun is a type of extremely large shotgun used in the 19th and early 20th centuries for shooting large numbers of waterfowl for commercial harvesting operations and private sport. “Used for duck hunting” isn’t the right expression for aiming this piece of artillery in the general direction of a flock of ducks, firing, and spending the rest of the day picking up the carcasses.
In the early 1800’s the mass hunting of waterfowl to supply commercial markets with meat became a widely accepted practice. In addition to the market for food, women’s fashion in the mid 1800’s added a major demand for feathers to adorn hats. To meet the demand, professional hunters developed custom built extremely large shotguns (bore diameters up to 2″) for the task. These weapons were so cumbersome that they were most often mounted on long square-ended flat-hulled boats called punts. Hunters would typically use a long pole to quietly push their punt into range of a flock of waterfowl resting on the lake and, POW. A single shot from one of these huge guns could kill as many as 50 birds. To increase efficiency even further, punt hunters would often work in groups of 8-10 boats. By lining up their boats and coordinating the firing of their single shot weapons, entire flocks of birds could be “harvested” with a single volley. It was not unusual for such a band of hunters to acquire as many as 500 birds in a single day. Because of the custom nature of these weapons and the lack of support by the weapons industry, they were often rather crude in design. Most were sturdy hand-built muzzle loaders fired with percussion caps.
The Punt Guns were too big to hold and the recoil so large that they were mounted directly on the punts used for hunting, hence their name. Hunters would maneuver their punts quietly into line and range of the flock using poles or oars to avoid startling them. Generally the gun was fixed to the punt, thus the hunter would maneuver the entire boat in order to aim the gun. The guns were sufficiently powerful, and the punts themselves sufficiently small, that firing the gun generated so much force that it pushed the boat back.
In the United States, this practice depleted stocks of wild waterfowl and by the 1860s most states had banned the practice. The Lacey Act of 1900 banned the transport of wild game across state lines, and the practice of market hunting was outlawed by a series of federal laws in 1918.
