Rifle ammunition

These primers can be used not only in small arms but also in some pyrotechnic devices and fuzes. All simple primers are small in size, 0.21 to 0.31 inch in diam and 0.12 to 0.23 inches long for rifle ammunition and slightly Smaller for carbines. They contain only one small charge of primary expl or a mixture which must have sufficient sensitivity to be initiated either by the crushing or stab action of a firing pin...

Fuze, PD M89- It is a single-action type providing super quick functioning on target impact. It arms at relatively low speeds of rotation and is intended for use in 57-mm recoilless rifle ammunition. The fuze (See Fig 1-83) is made up of either a one piece A1 body (E), or, as an alternative, of two parts.- Mechanism consists of a lightweight firing pin (D) seated in a cavity at the forward...

Smokeless powders, solid low explosives, are virtually smokeless in comparison to black powder. They are also less susceptible to damp, store better, are more powerful, and bum at a more easily controlled rate. These benefits come with the disadvantage that they bum hotter and cause greater damage to the barrels of weapons in which they are used extensively as ammunition propellants. The length of a weapon s barrel and other ballistic requirements result in smokeless powder for pistol ammunition being in flakes, which bums quickly, while slower burning balls, cylinders, or tubes are used for rifle ammunition riflepowder). There are three types of smokeless powder ... 

Rifle ammunition was produced in two publicly owned plants run by the army, and reached a daily production of 3.4 million cartridges in 1918, with a total wartime production of 3,616 million pieces. In the meantime, domestic private firms supplied the army with 700 million artillery shells, 7.3 million shells for trench mortars, and 880,830 bombs for aerial use. Because the Italian chemical industry lagged behind the metallurgical and mechanical industries, in 1918 there were more cartridges and shells made than filled. ...
