The name, derived from an old English practice of bore measurements in gun-making which refers to a nominally 4-gauge bore, that is, a bore diameter that would accommodate a pure lead round ball weighing 1 ⁄ 4 of a pound. This would imply a bore diameter of 1.052-inch (26.7 mm), however in practice the bore diameter varied greatly as, in ...
Note: Use of this table for estimating bullet masses for historical large-bore rifles is limited, as this table assumes the use of round ball, rather than conical bullets; for example, a typical 4-bore rifle from circa 1880 used a 2,000-grain (4.57 oz; 129.60 g) bullet, or sometimes slightly heavier, rather than using a 4-ounce (110 g) round ...
Due to the velocity limitations of black powder and lead—usually around 460 metres per second (1,500 ft/s)—the only way to increase penetration was to make a larger gun. The largest-bore guns in common use (and bore rifles with the advent of breech loading and rifling in the late 19th century) included the-4 bore, using a 130-gram (2,000 gr ...

The bore designations are only an approximate relationship to the actual weight of the projectile when it was applied to modern artillery. The table below lists the metric and Imperial calibres of various British weapons, which utilised the standard after 1919:
The civilian version of the KS-23 is the ТОZ-123 Selezen'-4 ("Drake-4") (ТОЗ-123 «Селезень-4»). It is manufactured by Tulsky Oruzheiny Zavod and features a smoothbore design, making it more similar to a traditional shotgun, and is chambered in standard 4 gauge. The first shotgun was made in 1995. [5]

Gun No. 213 had a liner. The gun was described as a 5-inch (127 mm) gun but with a 4-inch bore in the 1902 handbook, this indicated its higher power and also the fact the barrel was actually more the size of a 5-inch/40 caliber gun than a 4-inch gun. The ammunition was about 7 lb (3.2 kg) heavier than a 4-inch/40 caliber round.
