Nosler Partition Bullets .25 cal .257" 120 gr SPT 50/ct

The Nosler Partition Bullets .25 cal .257" 120 gr SPT 50/ct represent a benchmark in terminal ballistics for hunters and precision reloaders who require absolute reliability. These projectiles are specifically engineered for quarter-bore rifles, providing a heavy-for-caliber weight that excels in both penetration and energy transfer on medium to large game. Whether you are building a custom load for a high-velocity .25-06 Remington or a classic .257 Roberts, these bullets offer the consistency necessary for professional-grade field results. The Spitzer point profile ensures a streamlined flight path, making them a preferred choice for marksmen operating in varied environmental conditions.

At the core of the Nosler Partition Bullets .25 cal .257" 120 gr SPT 50/ct is a dual-lead-alloy core separated by a structural copper partition. The front core is protected by a fully tapered jacket that is thin at the mouth to facilitate immediate expansion even at lower impact velocities, while the jacket gradually thickens toward the center to control the mushrooming effect. This design allows the front section to expand violently for massive shock while the rear core remains intact to ensure deep, bone-crushing penetration. This mechanical "partition" is what prevents the projectile from over-fragmenting, maintaining the weight retention needed for ethical stops on tough targets.

Experienced handloaders will find the Nosler Partition Bullets .25 cal .257" 120 gr SPT 50/ct highly compatible with a wide array of smokeless powders and standard .257 diameter barrels. The 120-grain weight provides a high sectional density, which translates to superior tracking through dense tissue and better stability in crosswinds compared to lighter projectiles. These bullets are sold in a 50-count box, allowing for meticulous load development and sufficient quantities for a full hunting season. Relying on this proven architecture ensures that your rifle performs at its peak when the shot truly matters in the field.
