Typical 8 bores weighed 15 to 16 lb (6.8 to 7.3 kg), and fired a 1,250 gr (81 g) conical bullet at around 1,500 ft/s (460 m/s) or an 860 gr (56 g) spherical ball at around 1,650 ft/s (500 m/s), both with 10 to 12 drams (17.72 to 21.26 g) of black powder, [1] although sometimes heavier charges of 14 drams (24.82 g) were used, generally in Africa.
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 ...
For the purpose of this list, the development of large-calibre artillery can be divided into three periods, based on the kind of projectiles used, due to their dissimilar characteristics, and being practically incommensurable in terms of their bore size: Stone balls: Cannon of extraordinary bore, which fired stone balls, were first introduced ...
Round shot or solid shot or a cannonball or simply ball A solid spherical projectile made, in early times, from dressed stone but, by the 17th century, from iron. The most accurate projectile that could be fired by a smooth-bore cannon, used to batter the wooden hulls of opposing ships, forts, or fixed emplacements, and as a long-range anti ...
Shotgun cartridges are generally measured by "gauge", which is the weight, in fractions of a pound, of a pure lead round ball that is the same diameter as the internal diameter of the barrel. In Britain and some other locations outside the United States, the term "bore" is used with the same meaning. [5]
A certain amount of windage (in this case meaning that the bore is designed slightly wider than the cannonball) allows the ball to fit down the bore, though the greater the windage the less efficient the propulsion of the ball when the gunpowder is ignited. To fire the cannon, the fuse located in the vent is lit, quickly burning down to the ...
The caliber was still measured in bore or gauge—10, 8, 6, 4 bore, and 2 bore—or the guns were named by number of projectiles per pound. The projectiles were lead round balls or short conical slugs, sometimes hardened with antimony .
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball.
