The
7.92×107mm 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
7.92×57mm Mauser
cartridge, but was much longer (107 mm as opposed to the 57 mm of Mauser cartridge) and was modified to provide higher
muzzle velocity
and hence more penetrating power.
History
[
edit
]
DS 7.92mm anti-tank rifle ammunition - a single cartridge and an entire box.
In the 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 German-made Hagler bullets proved the possibilities of such ammunition in perforation of steel plates, the National Ammunition Factory in
Skar?ysko-Kamienna
was ordered to develop its own 7.92 mm cartridge with a
muzzle velocity
of over 1,000 m/s (3,300 ft/s). After a series of tests, a new DS cartridge was proposed.
The DS ammunition was based on a standard 7.92 mm cartridge used by both the Mauser rifles and the Polish
Karabinek wz. 29
. The length of the cartridge was extended to 131.2 mm (5.17 in) and the overall
weight
reached 64.25 g (2.266 oz). After an additional series of tests, the initial copper coating was replaced with a coating made of
brass
(an alloy of 67% copper and 23% zinc).
