For shooters running Schmidt Rubin K31 rifles or other 7.5×55 Swiss platforms, the PPU 7.5×55 Swiss 174 grain Full Metal Jacket load delivers consistent velocities and clean extraction from Boxer-primed brass. This 7.5×55 Swiss ammo pushes a 174 grain FMJ projectile at 2526 feet per second, producing 2478 foot-pounds of muzzle energy — squarely in the middle of Swiss military ballistic specs. Prvi Partizan manufactures this ammunition in Serbia using non-corrosive primers and reloadable brass cases, giving range shooters and collectors a cost-effective practice round that matches the dimensions and pressures of original GP11 loads.
Load Profile
PPU chambers this round to modern SAAMI pressure standards, which exceed the design limits of early Model 1889 Schmidt-Ruben actions. Shooters with K31, G96/11, or commercial Vetterli conversions can safely fire this load. The 174 grain bullet weight and 2526 fps velocity replicate the trajectory of Swiss GP11 military ammunition, making it suitable for zeroing at known distances and practicing with surplus rifles.
