Nosler Partition 25 Cal .257 115gr Spitzer 50/Box

The Nosler Partition in 25 Caliber (.257) is a premium 115 grain Spitzer reloading bullet engineered around Nosler's signature dual-core design. A rear lead core is partitioned from a forward lead-alloy core by a solid metal barrier, anchoring mass on impact so the front core mushrooms into a large wound channel while the rear core keeps driving forward for deep penetration on heavy game.

A fully tapered copper alloy jacket wraps both cores for controlled expansion and reliable weight retention. The Spitzer profile on a flat base delivers the accuracy handloaders expect from the Partition line, with a published BC of 0.389 and sectional density of .249. Each bullet measures 1.145" overall at 0.257" diameter with a lead tip and no cannelure.

Recommended for rifle hunting applications on medium and large game when driven at appropriate velocities. Supplied as 50 bullets per box, ready for handloading in 25-caliber cases.
