Quality hunting ammunition designed for maximum performance and reliability. Premium hunting bullets are matched with select powders, primers and brass to create a reliable, hard-hitting hunting cartridge. Nosler Partition Bullets feature a fully tapered jacket that ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at high or low velocities. Nosler’s integral Partition supports the expanded mushroom and retains the rear lead alloy core. The enclosed rear core retains more than half the original bullet weight for deep penetration. This ammunition is new production, non-corrosive, in boxer primed, reloadable cases
