Product DescriptionNosler Partition bullets are built for dependable hunting performance, combining controlled expansion with deep penetration. Each projectile uses a fully tapered copper-alloy jacket that initiates expansion quickly while progressively thickening to help regulate upset across a wide range of impact velocities. The signature dual-core design with an integral partition supports the expanded front core while helping keep the rear core intact for strong weight retention and straight-line penetration. Special crimp locks add strength to resist deformation under heavy-magnum pressures, making these 140-grain Spitzer bullets an excellent choice for 6.5mm/.264 reloading applications such as 6.5 Creedmoor.Product Highlights Proven Nosler Partition dual-core design for controlled expansion and deep penetration on game Fully tapered copper-alloy jacket promotes rapid upset while helping control expansion at varied velocities Integral partition supports the expanded mushroom and helps retain the rear core for reliable weight retention Spitzer profile for strong in-flight performance and hunting accuracy Special crimp locks add strength and help resist deformation under heavy-magnum pressuresSpecs Brand: Nosler Product Line: Partition Manufacturer Part Number: 16321 UPC: 054041163217 Bullet Type: Spitzer Caliber/Diameter: 6.5mm / .264 Bullet Weight: 140 grain Quantity: 50 bullets per box Sectional Density: 0.287 Materials: Copper-alloy jacket with lead alloy core Country of Origin: USADisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
