The benchmark for hunting bullets since 1948 Nosler's Partition bullet is the cornerstone upon which the entire company was founded.The Nosler Partition is designed with a fully tapered copper-alloy jacket which ruptures instantly on impact curling the jacket uniformly outward. The dual-core design assures rapid expansion of the foremost core while Nosler's integral partition supports the expanded mushroom allowing the enclosed rear core to remain intact retaining more than two-thirds the original bullet weight for deep penetration. The Nosler Partition special lead-alloy dual-core provides superior mushrooming characteristics at virtually all impact velocities on any game.
