Nosler 243 Winchester Ammunition 85 Grain Partition Spire Point Box of 20

The Nosler Partition is still the benchmark by which all modern bullets are measured. Nosler’s special lead-alloy, dual-core provides superior mushrooming characteristics at virtually all impact velocities.  The 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 jacket uniformly outward at high and low velocities.  Nosler’s integral partition supports the expanded mushroom and retains the rear lead-alloy core. The enclosed rear core retains more than two-thirds of the original bullet weight for deep penetration.  Every Partition® bullet in the Nosler® line delivers optimum length, weight and ogive design for maximum in-flight and terminal performance.
