Nosler Partition 25 Cal .257 100gr Spitzer 50/Box

The Nosler Partition is one of the most iconic premium hunting projectiles ever designed, and the 25 Caliber 100 grain Spitzer brings that heritage to handloaders building hunting loads in .257" bore rifles. The Partition's signature feature is its dual-core construction: a fully tapered copper-alloy jacket ruptures instantly on impact and curls the jacket uniformly outward, allowing the front portion to expand while the rear core stays intact. The rear core is locked in place by a special crimp so it retains more than half the original bullet weight for deep, straight-line penetration through heavy muscle and bone.

This 50-count box delivers the .257" diameter, 100 grain Spitzer profile that handloaders have trusted for decades. Specifications include a sectional density of .216, a ballistic coefficient of .377, a flat base, and a lead Spitzer tip. The jacket is copper, the core and tip are lead, and the bullet is supplied with no cannelure for clean, consistent seating across a wide range of 25 caliber rifle cartridges.

Recommended for hunting and intended for rifle use, the 100 grain Partition gives reloaders a proven projectile for any 25 caliber hunting application where reliable expansion and deep penetration are required. Each box contains 50 bullets.
