Special Features

• The dual-core construction separates the bullet into two distinct lead-alloy sections divided by an integral copper partition, allowing the front core to expand aggressively on impact while the sealed rear core drives deep penetration regardless of velocity.
• The fully tapered copper-alloy jacket ruptures instantly at the thin jacket mouth, then thickens progressively toward the base to control expansion and curl the jacket uniformly outward at both high and low impact velocities.
• The integral partition supports the expanded mushroom and locks the rear core in place, retaining more than two-thirds of the original bullet weight for reliable penetration on tough game animals.
• Special crimp locks add structural strength to the bullet body, resisting deformation under elevated pressures generated by magnum cartridges without affecting terminal performance.

Practical Benefits

• These bullets are compatible with 30 caliber cartridges including the .30-06 Springfield, .308 Winchester, .300 Winchester Magnum, and .300 WSM, giving you one proven component across the most widely used 30 cal hunting platforms.
• The 180-grain weight delivers a sectional density of 0.271, producing the penetration depth needed for clean, ethical kills on deer, elk, black bear, and similar medium to large game at all field distances.
• The Partition design performs consistently across the full velocity spectrum from close-range brush shots to long-range open-country opportunities, eliminating the need to swap components as hunting conditions change.
• If you reload for a 30 caliber rifle and want a hunting bullet with a field-proven track record across decades of use on the world's most demanding game, the Nosler Partition (16331) gives your handloads the terminal reliability and weight retention your hunting setup deserves.
