| | The New Martini-Enfield Rifle |
 | | The bore of the Martini-Enfield is 0.40 inch in diameter, and is rifled with a ratchet rifling, the grooves being either seven or nine in number, and the twist one turn in 15 inches. |
 | | As regards muzzle velocity, the French, Austrian, Russian, and German rifles are all superior to the Martini-Henry, and all inferior to the Martini-Enfield. |
 | | Although rifling of Metford's design was not considered during the original Martini-Henry trials, it soon became clear that his barrels, rifled with five or seven grooves of segmental rifling so shalllow as to be hardly perceptable, shot so well that they could not be ignored. |
