At the onset of the industrial revolution, people were looking at ways to mass-produce and commercialize nearly everything. But what about something as manual as duck hunting? Was there any way to mass-hunt ducks with some sort of firearm capable of knocking, say, 50 to 100 ducks out of the air all at once? Yes, in fact, there was. It was called the punt gun.
Back in the first decade of the 19th century, there existed a monster of a shotgun. Each of these guns was custom made for the ambitious hunter that wanted one, but in all cases, the barrels were somewhere between ten and thirteen feet in length. Most were muzzle-loaded while others had false breaches to load the over one pound of ammunition.
The overly-large shotgun weighed over 100 lbs. While many of the existing photos are of hunters jokingly posing like they're using as a conventional shotgun, realistically, the recoil would've likely ripped someone's arm off.
Instead, the gun was fastened to a punt — a flat-bottomed rowboat. The firer would position the boat towards a large flock of waterfowl and fire. The massive amount shot deployed with a single firing would most certainly take out enough birds to supply the hunter for an entire day. In order to properly mount the gun, the boats themselves needed to be specially-reinforced to account for the immense, destructive force.
But these guns have nothing on the granddaddy of all punt guns - Irish Tom, the world's largest. Created in Great Britain in the 1930s by W.W. Greener and the Whitworth Factory of Manchester, this gun weighed over 300 lbs, had a 14' 1" barrel, and fired 3lbs 2oz of buckshot. The original owner, Stanley Duncan, claimed his best shot downed 100 ducks.
Just a handful of market hunters equipped with punt guns was enough to nearly drive ducks to extinction, ultimately leading to the gun being outlawed. Original and modern remakes can be scarcely found by collectors.
In the UK, punt guns are also used ceremoniously. Ever since Queen Victoria's Diamond Jubilee in 1897, 21 punt guns have been fired during every coronation and jubilee in Cowbit Wash, Lincolnshire.
