7.5X55mm Swiss 20 Rounds Ammunition Prvi Partizan 174 Grain Jacketed Soft Point

The 7.5X55mm Swiss (7.5X55mm Swiss Schmidt-Rubin) dates back to 1889, originally with a bullet diameter of .299-inch. In 1911 a 174-grain spitzer bullet was adopted and the bullet diameter was changed to .308-inch (same as the American .30-caliber). The 7.5X55mm Swiss was chambered to succeeding variations of the Schmidt-Rubin straight-pull action, but the 1911 version was faster and loaded to higher pressure, so current loadings must not be used in original Model 1889 rifles. The standard military load used a 174-grain bullet at 2560 fps. Current factory loads are similar, so performance is essentially the same as the 7.62X51mm NATO. — Craig Boddington
