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 ...
Model 1849 Berdan Sharps rifle. Sharps was issued a patent for his design of a breech-loading rifle on September 12, 1848. The deficiencies of the Hall rifle may have caused Sharps to adopt his new design. The Sharps rifle was designed with a vertical dropping block action, operated by a lever which also served as a trigger guard.

Sharps rifles are a series of large-bore, single-shot, falling-block, breech-loading rifles, beginning with a design by Christian Sharps in 1848 and ceasing production in 1881. They were renowned for long-range accuracy.
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 ...
e) Vintage (pre 1939) rifles, shotguns and punt guns chambered for the following cartridges expressed in imperial measurements: 32 bore, 24 bore, 14 bore, 10 bore (5 ⁄ 8" and 2 + 7 ⁄ 8" only), 8 bore, 4 bore, 3 bore, 2 bore, 1 + 1 ⁄ 8 bore, 1 + 1 ⁄ 4 bore and 1 + 1 ⁄ 2 bore, and vintage punt guns and shotguns with bores of 10 or greater.
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 ...
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
