7.92×107mm DS
rifle cartridge
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 the Mauser cartridge) and was modified to provide higher muzzle velocity and hence greater penetrating power.
History
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 Skarżysko-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).
This brief starts where responsible research should: with the source description of “7.92×107mm DS” as rifle cartridge. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as rifle cartridge. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 24, 2025. The linked authority identifier is Q259245. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1931.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
