Nosler Partition spitzer component bullets in 6.5mm .264 diameter at 140 grains (16321) are a premium big game hunting projectile built for reloaders who want the proven dual-core construction and controlled expansion that has defined hunting bullet performance for over seven decades. These 6.5mm big game reloading bullets for cartridges like the 6.5 Creedmoor and 6.5x55 Swedish come 50 per box and deliver reliable expansion and deep penetration at virtually all hunting impact velocities.

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 across 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 6.5mm cartridges including the 6.5 Creedmoor, 6.5x55 Swedish, .260 Remington, and 6.5-284 Norma, giving you one proven component across multiple 6.5mm hunting platforms.
• The 140-grain weight delivers a sectional density of 0.287, producing the penetration depth needed for clean, ethical kills on deer, elk, 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 6.5mm rifle and want a hunting bullet with a field-proven track record on medium to large game, the Nosler Partition (16321) gives your handloads the terminal reliability and weight retention your hunting setup deserves.
