History of 7.5x55mm Swiss Ammunition

Eduard Rubin, a Swiss Army Lieutenant Colonel, designed the 7.5x55mm Swiss cartridge in 1889. The Swiss military was using a 10.4x38mm rimfire rifle at the time. The 7.5x55 Swiss used a bullet with a smaller diameter (.304 inches), and was among the first cartridges to investigate the idea of firing smaller and lighter bullets at high velocity which began to gain ground among governments and builders of military rifles. The cartridge was chambered in the Schmidt-Rubin Model 1889 rifle which the Swiss Army adopted for service in 1889.  An interesting fact about the cartridge is that the bullet, configured as a steel capped round nose and weighing 211 grains, used a paper patch. This was common at the time and increased the time required for manufacturing.

The 7.5x55mm Swiss was modified several times during its first three decades or so to stay abreast of new technologies and components. The GP11 version was introduced in 1911. The GP11 has proven accuracy, and this version of the cartridge has been used effectively in many target competitions. The round appeared on the scene in 1911 and remained in service for approximately eighty years. This rimless bottleneck cartridge was first introduced for bolt action rifles, and it spent the last years of its service life being fired from the select fire Stgw57.

Today Hornady, Prvi Paritizan, and Wolf, among others, manufacture 7.5x55mm Swiss ammunition. The 174 grain FMJ spitzer point is most common load. The bullet leaves the muzzle with a velocity of about 2,500 feet per second and generates a muzzle energy greater than 2,500 foot pounds. The GP11 ammo used by the Swiss military is loaded a little hotter and pushes the same bullet to more than 2,600 feet per second.

In the United States today, the 7.5x55mm Swiss is mostly seen chambered in surplus Swiss K31 rifles. The K31 is not as popular as other bolt action rifles of the same era, but it does perform well for hunting and target shooting.
