Nosler Partition Bullets .25 cal .257" 115 gr SPT 50/ct

Nosler Partition Bullets .25 caliber .257" 115 grain Spitzer Point (SPT) are premium reloading components engineered for consistent terminal performance across a wide velocity range. The Partition design combines a thin, fully tapered jacket at the nose with a thicker mid-section and hardened rear core, delivering the controlled expansion and weight retention demanded by precision rifle shooters and hunters pursuing medium to large game.

The jacket is engineered to initiate expansion immediately upon impact, while the graduated thickness slows jacket separation and controls mushroom growth. Crimp locks in the rear core secure the lead alloy base, ensuring the expanded mushroom remains intact even at marginal velocities or angled impacts. At higher velocities typical of .25 caliber rifle loads, the partition prevents over-expansion and fragmentation, preserving momentum and penetration. The 115-grain Spitzer Point profile is ballistically efficient and optimized for the velocity envelope of .25-06 Remington and similar cartridges.

This ammunition component is suited for hand-loaders developing match-grade or hunting loads who require predictable bullet performance and tight quality control. The 50-round count per box supports component testing, load development, and small-batch production. Nosler Partition Bullets are recognized within the precision reloading and long-range hunting community for consistency in weight, concentricity, and terminal performance. Shooters reloading .25 caliber cartridges will find these bullets compatible with standard .257" diameter reloading dies and tooling.
