7,92 ds

The 7,92 DS was a Polish 7.92 mm anti-tank ammunition designed specifically for use with the Karabin przeciwpancerny wz.35 anti-tank rifle. It was based on a standard 7.92 Mauser cartridge, but was much longer (107 mm as opposed to 57 mm of Mauser cartridge) and had was largely modified to provide higher muzzle velocity and more penetrating power.

History

In late 1920s the Polish General Staff started the development of a light anti-tank weapon for the Polish infantry. In 1931 Lt. Colonel Tadeusz Felsztyn from the Institute of Armament Technology in Warsaw started the first tests of various low-calibre cartridges. After the tests of a German-made Hagler bullets proved the possibilities of such ammunition in perforation of steel plates, the National Ammunition Factory in Skarżysko-Kamienna was ordered to develop its own 7.92 mm bullet with a muzzle velocity of over 1000 metres per second. After a series of tests, a new DS bullet was proposed. The DS ammunition was based on a standard 7.92 mm bullet used by both the Mauser rifles and the Polish karabinek wz.29. The length of the bullet was extended to 131.2 mm and the overall weight reached 64.25 g. After an additional series of tests the initial copper coating was replaced with coating made of brass (an alloy of 67% of copper and 23% of zinc).
