.30-170 R.N. Nosler Partition Bullets 50pcs

The Nosler Partition bullets in .30 caliber and 170 grains with a round nose profile 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 completely tapered, these projectiles achieve immediate and controlled expansion upon impact, causing the jacket to uniformly peel outward in a consistent manner. The innovative dual-core construction features a front core designed for rapid expansion, while the integral Nosler partition acts as a robust barrier, maintaining the expanded mushroom shape and ensuring the rear core retains over two-thirds of the bullet's original mass for superior penetration through dense muscle and bone.

This advanced bullet architecture delivers expansive wound channels and maximizes kinetic energy transfer, critical parameters for ethical and effective big game hunting. The round nose tip combined with a flat base enhances terminal ballistics at short to medium engagement distances, while also providing excellent feeding reliability and ease of reloading for handloaders specializing in metallic and semi-metallic cartridge assembly.
