The shorter barrel makes the weapon easier to maneuver ...
To better withstand that power, fire lance barrels were made of metal, [3] At the same time, the shrapnel was replaced by projectiles whose size and shape filled the barrel more completely. [4] The result was the hand cannon, with metal barrel, high-nitrate gunpowder, and a properly sized projectile. [8] [9]

As far back as 1787 a Frenchman by the name of M. Magne de Marolles gave an account of choke-boring, though he argued against it. [3]Some sources state that the first pioneer was a Czech named Dominik Brandejs, who made shotguns with a choke in order to reduce the dispersion of shots, but his design was not popular in the 1820s.
A number of gun companies have tried to produce Model 1887/1901 shotguns that could chamber modern, smokeless shotgun shells—largely for the cowboy action shooting discipline—but with little commercial success. Three firearm companies have managed to produce viable models for the commercial firearms market by utilising the easier to produce ...
The .410 bore is the smallest shotgun size which is widely available commercially in the United States. For size comparison purposes, the .410, when measured by gauge, would be around 67- or 68-gauge (it is 67.62-gauge), The .410 is often mistakenly assigned 36-gauge. The 36 gauge had a 0.506" bore.
