Nosler Partition 25 Caliber 120 Grain Spitzer Reloading Bullets, Part Number 35643, 50 Count

Nosler Partition bullets are engineered for reliable in-flight stability and controlled terminal performance during hunting applications. Part Number 35643 features a 120-grain Spitzer profile designed for 25 caliber reloading. The bullet’s streamlined shape supports consistent flight, while the lead tip initiates expansion on impact. Each box contains 50 reloading bullets for handloaders seeking dependable performance from carefully assembled hunting ammunition.
The Partition design uses a fully tapered copper-alloy jacket that opens at the thin front section while gradually thickening toward the bullet’s axis. This construction helps regulate expansion across a broad range of impact velocities, allowing the jacket to curl outward in a controlled manner. Nosler’s integral partition supports the expanded front section and helps preserve the rear lead-alloy core for deep penetration and reliable weight retention.
Special crimp locks add structural strength and help resist deformation under the elevated pressures associated with heavy magnum cartridges. The lead tip and lead core work with the copper-alloy jacket to provide a proven hunting bullet configuration, while the absence of a cannelure maintains the intended streamlined design. With a .257-inch bullet diameter, a .260 sectional density, and a 25 caliber designation, Nosler Partition bullets are a practical choice for hunters and reloaders who prioritize controlled expansion, penetration, and consistent component quality. Use only in accordance with published load data and safe reloading practices.
