The 12-pdr rifle was designed in the early 1850s by British manufacturer Joseph Whitworth, who had recently been contracted to improve the Pattern 1853 Enfield.During his experiments with the Enfield, Whitworth was inspired to begin experimenting with a hexagonally-rifled barrel; Whitworth would later apply these principles to his field guns.
It was produced by Armstrong Whitworth, Elswick and used on Royal Navy warships, exported to allied countries, and used for land service. [4] In British service "12-pounder" was the rounded value of the projectile weight, and "12 cwt (hundredweight)" was the weight of the barrel and breech, to differentiate it from other "12-pounder" guns.
Muzzle-loading artillery came in smoothbore and rifled form, the rifled guns increasingly taking over from the smoothbores as time past and technology improved. Most were made of bronze because of a lack of metallurgic technology, but cast and wrought-iron guns were common as well, particularly later on.
The Whitworth rifle was designed by Sir Joseph Whitworth, a prominent British engineer and entrepreneur. Whitworth had experimented with cannons using polygonal rifling instead of traditional rifled barrels, which was patented in 1854. The hexagonal polygonal rifling meant that the projectile did not have to bite into grooves as was done with ...

From a design standpoint, the weapon was unique. Like all of Whitworth's designs, the weapon had a hexagon-ally rifled barrel. It was also a breechloader, an unusual feature for the time. The piece had exceptional range and accuracy, being capable of firing a 3-pound shell over 9,500 yards. [4]
The gun used polygonal rifling, a principle invented by Whitworth in 1853.The concept was to use the hexagon to impart a very rapid spin to the projectile. The method of manufacturing the rifling was thus described by the Report of the Armstrong & Whitworth Committee of the British War Office (1866):
Whitworth was born in John Street, Stockport, Cheshire, where the Stockport Courthouse is today.The site is marked by a blue plaque on the back wall of the courthouse. He was the son of Charles Whitworth, a teacher and Congregational minister, and at an early age developed an interest in machinery.
