Nosler Partition bullets in caliber 25 and 100 grains have been the benchmark standard 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 initiate immediate and controlled jacket expansion upon impact, causing the jacket to uniformly peel outward. The innovative dual-core construction features a rapid expansion frontal core, while the integral Nosler partition acts as a robust barrier, maintaining the integrity of the rear core. This design ensures retention of over two-thirds of the bullets original mass, enabling deep and consistent penetration through dense tissue and bone.
This sophisticated bullet architecture produces expansive wound channels and maximizes kinetic energy transfer, critical parameters for ethical and effective big game hunting. The bullet is configured with a flat base and a streamlined Spitzer tip, optimizing its external ballistics for superior aerodynamic stability, flatter trajectories, and enhanced downrange accuracy. Additionally, these design elements facilitate reliable metallic and semi-metallic reloading processes, making Nosler Partition bullets a preferred choice among handloaders seeking consistent performance and precision.
