The answer to the question of whether there is a one gauge shotgun shell is yes. One gauge shotguns were popular in the market hunting days.

 All shotguns are classified by gauge, and this is a measure that relates to the size of the shotshell designed for a specific diameter of the smooth shotgun bore. When you think about shotguns the first thing that comes to mind is what gauge you are using. Therefore the real question becomes, is there a one gauge shotgun shell? 

One of the earliest designs of shotguns was called the punt guns and they were one gauge and sometimes referred to as one-bore as they had a diameter of 1.669-inches which is 42.42 mm. The barrel length would extend up to eight feet. Despite all these massive measurements, you should note that the 1-bore punt gun was among the smaller designs of punt guns as some had up to four inches of bore size. 

The good thing about guns is that there is a whole new world out there to discover. A rich history behind every model and caliber that is used. Shotguns are not any different from rifles and handguns in history. 

Also, the previous designs of punt guns mainly featured guns with black powder muzzle-loaders, however, they used massive shells. Hence a one gauge shotgun can fire a full pound of lead. Earlier uses of punt would see hunters mount them on to a rowboat for commercial duck hunting, The idea was to hit as many birds with a single shot.

What are Punt Guns?

To understand a punt gun you must think of it as an extremely large shotgun that grew in popularity around the late 19th and early 20th centuries. The primary goal was shooting at large numbers of birds and waterfowl to meet the rising demand for commercial bird harvesting operations. 

The design of the punt gun is too large for one person to fire from the shoulder and could not even be carried by an individual. The difference with punt guns and other modern heavy artillery is that it takes only one individual to aim and fire at targets once mounted. In most cases, the mount would be on a watercraft. 

Early models are similar to the modern versions of shoulder weapons however later variations do not have the full-length stock. But they come with special mounting hardware that is fixed to the gun so that you can fit the punt gun to a pintle.

How Much Does One-Gauge ShotGun Shells Cost?

Following the history of shotguns, it has been several decades since shotguns larger than 10-gauge have been made and the same applies to one-gauge shotshells. Even though it is still possible to find one-gauge shotshells, they are completely sold as individual collector’s items and hence attract collector prices.  

The one-gauge fires a full pound of lead pellets and historically, it is the largest commercially produced ammo. In modern times, this feat belongs to the 10-gauge shotshells and has varying prices dependent on brand and material used. 

Another point to note on smaller gauge shotshells is that history shows the mass production of both the 4-gauge and 8-gauge ammo but they were also discontinued. It is even difficult to find the shotshell ammo if you have the shotgun that can fire. Most of these shotguns(8-gauge and 4-gauge) were fired using separate components sometimes instead of shells.  

The 1-gauge shotshells were massive and therefore the bore diameter of the shotgun (punt gun) had to be massive as well. Most Punt guns are custom built and therefore, there is no standard measurement for what a punt gun should measure. Hence the basic definition of a punt gun is a shotgun that is too big to be used normally, and one must us
