After the end of WW1 and into the early 1920’s a lot of research went into the development of not just an anti-tank rifle, which soldiers first encountered during the last stages of the War, but also to defeat artillery pieces as a more economical means...

From a note in the IAA Journal 466:25 (March/April 2009). The VBR-B 7.92x24mm caliber was first developed in Belgium by Rik Van Bruaene on 14 April 2005 as a new defence cartridge for a PDW (Personal Defensive Weapon) with the first official pressure measurements and...

   This is the predecessor of the 7.62x24.5mm sub caliber cartridge and was used as an anti-tank spotter round. It was phased out of service when the 7.62mm became standard, although it remained in use to some extent. The case was not based on the...

   This was a development by Polte Magdeburg during the years between WW1 and WW2 similar to the 7x45 Polte when the Germans did research regarding short cased intermediate cartridges that culminated in the 7.92 Kurz. The Swiss were also doing research in...

   During 1900 the Dutch put together a commission to study and evaluate the procurement of machine guns for the Dutch Military. Extensive test were performed with a variety of guns available and in the end, the most cost effective gun was selected by the...

The Norwegians came to the same conclusion as most European Nations during the years post WW1 and that was that their 6.5x55SE was not powerful enough for machine gun use. The 7.92x57 M.98 was in use in Norway, but they introduced a new caliber with the case extended...

This was an unsuccessful high velocity experimental cartridge by Rheinmetall-Borsig designed for aircraft machine guns. It appears to have been a parallel development with the 13mm machine gun. At that time during WW2, the Germans were on the defensive and were taking...

This was one of a series of experimental rounds started in 1931 for the Karabinek KP-32 anti-tank rifle designed by Józef Maroszek as his academic thesis at the Faculty of Engineering at the Warsaw University of Technology. Trials were done around 1934-35 by the...

With the introduction of tanks during WW1, the need quickly arose for infantry anti-tank weapons. Late in World War 1, Germans introduced the first heavy anti-tank rifle – the 13.35mm Mauser Tank Gewehr Model 1918 based on the 7.92mm Mauser Model 98 rifle. This new...
