The Nosler Partition is the bullet of choice for big game hunting anywhere in the world. The Partition's ability to control both expansion and penetration is rivaled only by its extreme accuracy. The bullet's integral partition supports the expanded mushroom while retaining the rear lead-alloy core. Crimp locks add strength to resist deformation under the pressure of heavy magnums. Lead-alloy dual-core provides superior mushrooming characteristics at virtually all impact velocities. Fully tapered copper alloy jacket ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet's axis controls expansion and curls the bullet uniformly outward at high or low velocities. Box of 50 rounds.
