The Federal FireStick is a proprietary polymer-hulled blank cartridge, introduced in 2020 for the Traditions NitroFire rifle. Containing 100 to 120 grains of Hodgdon 888 black-powder substitute and neither a primer nor a bullet, the round and the rifle designed for it were devised as a way of creating a gun that functions as closely to a modern rifle as possible whilst still being legal in ...

A muzzle-loading rifle is a muzzle-loaded small arm that has a rifled barrel rather than a smoothbore, and is loaded from the muzzle of the barrel rather than the breech. Historically they were developed when rifled barrels were introduced by the 1740ies, which offered higher accuracy than the earlier smoothbores.
This would imply a bore diameter of 1.052-inch (26.7 mm), however in practice the bore diameter varied greatly as, in muzzle loader days, shotgun gauges were custom made and often differed from the actual bore measurements. Commonly, 4 bores were closer to 0.935–0.955 in (23.7–24.3 mm) calibre, which is closer to 5 gauge.
A 12-gauge shotgun, nominally 18.5 mm (0.73 in), can range from a tight 18 mm (0.71 in) to an extreme overbore of 20 mm (0.79 in). Some also claim an increased velocity with the overbored barrels, up to 15 m/s (49 ft/s), which is due to the larger swept volume of the overbored barrel.

All of these have a distinct shoulder ...
The muzzle-loading design and weight of the iron placed design constraints on the length and size of naval guns. Muzzle loading required the cannon muzzle to be positioned within the hull of the ship for loading. The hull is only so wide, with guns on both sides, and hatchways in the centre of the deck also limit the room available.
