In the new arm, the Martini action is retained, the outside dimensions of the barrel are the same, but the bore is reduced from ·45 inch to ·4 inch. While the twist of the rifling is increased from 1 turn in 22 inches to 1 turn in 15 inches. The weight of the bullet is reduced from 480 grains to 384, the powder charge being the same as in the former rifle, 85 grains. A wooden hand guard is fixed over the breech end of the barrel to protect the hand of the soldier when the barrel becomes heated by rapid firing. The barrel is no longer imbedded in the fore-end of the stock; it was found that the exterior of the barrel was liable to rust from contact with the wood. The fore-end is now so shaped that the barrel simply lies upon it, held in place by the bands which surround both stock and barrel. The back sight is provided with a wind gauge, and a locking bolt secures the trigger when the arm is at full cock. A sword bayonet is substituted for the former triangular-shaped bayonet. A “quick loader” will be used with this arm. It hangs on the side of the body of the action, and holds six cartridges. The cartridges are acted upon by a spring which forces the head of the cartridge through an aperture in the lid, ready for the soldier’s hand. With this “quick loader,” six rounds can be fired in about 25 seconds, whereas, in loading from the pouch, 40 seconds are required. This description, of the new arm may be subsequently modified, as the recommendation of the Committee has not yet been confirmed. DIMENSIONS, &C., OF THE BREECH-LOADING ARMS OF THE BRITISH SERVICE.
