PRVI PARTIZAN BULLETS 303/.311 SPBT 180G 50PC

The .303/.311 180-grain FMJ BT bullets are designed for demanding shooters who demand predictable external ballistics and repeatable accuracy. The full metal jacket boat-tail geometry reduces air resistance and promotes stable rotation, maintaining a more linear trajectory over medium and long distances and significantly reducing wind drift. With a mass of 180 grains, the bullet offers a balanced ratio between kinetic energy and ballistic stability, enabling consistent impact patterns, especially in conservatively cut barrels in the .303/.311 format. The precisely manufactured jacket construction supports clean barrel penetration and minimizes deposits, ensuring consistent internal ballistics and easier targeting. The boat-tail design improves glide at higher speeds and optimizes the ballistic curve for increased efficiency in continuous firing exercises and precision shooting. Functionally, the geometry is optimized for reliable magazine and case guidance; The rounded dimensions and the tapered transition ensure trouble-free feeding in both manual and semi-automatic systems. Thermal stresses and pressure peaks are compensated for by the jacket's material-specific design, ensuring stable performance across different ammunition loads.
