Category: Hex Bore

The Whitworth rifle with its hexagonal bore set new standards in accuracy and in the early 1860s was used by keen long range riflemen in target shooting competition. By the late 1860s it was however being supplanted by other gunmakers using shallow groove rifling and hardened cylindrical bullets – notably Metford and Rigby. It is not uncommon to find Whitworth stock/lock fitted with such barrels as 19thC riflemen ‘upgraded’ their rifles, and over the years the original Whitworth barrel becomes separated.

A few pictures of original Whitworth rearsights illustrating that there was no single pattern; there are also further variants. All those shown are from full stocked Whitworth military style rifles. Whitworth rifles display in their construction many minor variations and finishing differences.

Lock plate on early Whitworth military rifle, dated 1858. This pre-dates the establishment of the Rifle Volunteer Movement and of the National Rifle Association by a year. The later use of the Whitworth rifle by Rifle Volunteers and others in competition organised by the NRA(UK) kept the rifle in the public gaze.

Curtis’s & Harvey No. 6 gunpowder was a popular choice in the 19th century for use with the Whitworth rifle. Contemporary loading instruction for the rifle refer to its use.

‘Miscellaneous Papers on Mechanical Subjects”, by Sir Joseph Whitworth (privately published in Manchester 1870). This leather bound and gilt edged collection of Whitworth papers arrived in the post a little while ago. Much of the content relates to Whitworth cannon.

Joseph Whitworth was born at Stockport in 1803 and was to become the foremost manufacturer of machine tools of his time. He was approached in 1854 by Lord Hardinge to investigate ‘the mechanical principles applicable in the construction of an efficient weapon.’ Unwilling to commit to the design of a complete set of machinery for manufacturing rifle muskets, Whitworth was asked to undertake the construction of the machinery for the rifle barrel only. His experiments revolutionised rifle design.
