.30-220 SSP Nosler Partition Bullets 50pcs
The Nosler Partition bullets in .30 caliber and 220 grains have been the benchmark for precision hunters and ballistic enthusiasts since their inception in 1948. Engineered with a fully copper alloy jacket that is meticulously tapered conically, these projectiles exhibit instantaneous expansion upon impact, causing the jacket to uniformly peel outward in a controlled manner. The innovative dual-core construction features a rapid-expanding front core, while the integral Nosler partition acts as a robust barrier, maintaining the integrity of the rear core. This design ensures that over two-thirds of the bullets original mass is retained, facilitating deep penetration through dense muscle and bone structures commonly encountered in big game hunting.
This advanced bullet architecture creates expansive wound channels and delivers substantial kinetic energy transfer, critical parameters for ethical and effective game harvesting. The bullet is further optimized with a flat base and a Semi-Spitzer ogive, enhancing its external ballistics by improving aerodynamic stability and velocity retention over extended ranges. These features also contribute to consistent chamber pressures and reliable feeding during metallic and semi-metallic reloading processes, making the Nosler Partition a favorite among precision reloaders and marksmen.
