Well if you can imagine a blackpowder smoothe bore shotgun about 10 ft long and capable of killing 40-100 ducks in one shot. It was used to kill large amounts of ducks as they sat rafted up on the water, and built around a small boat called a "Punt" thus the name Punt Gun The hunters would lay low in the boat and use the oar off the back sneak up on ducks typically by rounding the bends and would engage the ducks with this massive gun. It typically fires at or close to a pound of black powder and a pound or more of shot, but were often loaded with rocks, glass, nails, anything that was cheap and could kill a duck, accuracy wasn't as important as making a huge kill. Had so much power if is capable of blowing the boat backwards in the water a few feet. It was used during the duck rush where they were commercial harvested around 1840-1850. It completely decimated the duck population to the brink of extinction. Thus was banned, as well as commercial duck hunting. You can goggle search pictures on the net, its a very big impressive weapon. Basically like a long skinny cannon to kill ducks. I just have always wanted one so why the heck not make one, its cool to take to duck shows, or other outdoor demonstarations. Thats where I first seen one and I was hooked forever and halways wanted one but never needed one(Does anyone) but I figured I got a few extra bucks why not build one, they aren't perty by any means and the barrel and boat are the biggest cost, found a boat for $200.00 and a guy to make the barrel and breach for $400.00, the rest it big hunk of wood for make shift gun stock, a lock, and crude trigger. Often times the trigger was pulled with a rope. Hope this helps.
