Nosler 25 Cal 100gr Partition (50ct)

The Nosler 25 Cal 100gr Partition (50ct) is a premium bullet component crafted for handloaders and hunters targeting medium-game species who require deep penetration and high weight retention. This 0.257″-diameter, 100 gr projectile showcases Nosler’s renowned dual-core Partition® design: the front core expands to transfer energy while the rear core remains intact to maintain over two-thirds of its weight—ensuring reliable terminal performance on animals like deer, antelope, and feral hogs.

Featuring a spitzer profile and flat base, the bullet delivers stable flight and dependable feeding in bolt-action and magazine-fed rifles. With a G1 ballistic coefficient of approximately 0.335 and a sectional density of around 0.215, the Nosler 25 Cal 100gr Partition provides flat trajectories and strong downrange energy retention for precise shot placement.

Constructed with a fully tapered copper-alloy jacket and strict manufacturing tolerances, this bullet is engineered for uniform expansion and deep penetration. Although Nosler does not specify a minimum twist rate for this variant, handloaders consistently report excellent accuracy with barrels using 1‑9″ to 1‑10″ twists—ensuring stable performance with standard rifles like .25-06 Remington and .257 Roberts.

Each Nosler 25 Cal 100gr Partition bullet is produced in the USA and undergoes detailed inspection for jacket concentricity, core bonding, and weight consistency before being sealed in factory 50-count boxes. The consistent weight, form, and finish translate to repeatable precision and smooth chambering.

Ideal for hunting deer, antelope, hogs, and similarly sized game, the Nosler 25 Cal 100gr Partition (50ct) combines aerodynamic efficiency, deep penetration, and ethical terminal expansion—delivering the trusted performance serious hunters demand.
