Nosler Partition 25 Caliber 120 Grain Spitzer Bullets - Box of 50

The Nosler Partition 25 caliber 120 grain spitzer bullets represent over 75 years of proven field performance, earning their reputation as the go-to choice for handloaders pursuing medium-game hunting. Built on the dual-core design that made Nosler's name synonymous with reliable expansion and penetration, these bullets deliver the controlled mushrooming that separates a clean harvest from a long tracking job. Whether you're loading for varmint control or hunting deer-sized game, the Partition's time-tested construction ensures consistent results across a wide velocity range.

The engineering behind the Partition starts with a tapered copper-alloy jacket that initiates rapid expansion on impact. What sets it apart is the integral partition—a lead-alloy wall that separates the front and rear cores. When the bullet strikes, the forward core expands aggressively while the partition anchors the rear core, keeping it intact through the vitals. This two-stage expansion means you retain roughly two-thirds of the original bullet weight for deep, reliable penetration, even at lower velocities where some bullets fail to expand consistently.

Handloaders appreciate the Partition's forgiving nature across impact velocities and game sizes. The lead-alloy composition of both cores ensures mushrooming happens reliably whether you're pushing these 120-grain pills at conservative speeds or running them hot. A box of 50 gives you enough rounds to load a solid hunting season's worth of ammunition or test various load combinations to find the sweet spot in your rifle.

Frequently Asked Questions

What game can I hunt with 25 caliber 120 grain Partition bullets?

The 120 grain Partition in 25 caliber is well-suited for medium-game hunting where the cartridge's velocity and energy can be fully utilized. Suitability depends on your specific cartridge, load development, and local hunting regulations—consult reloading guides and game agency resources for your area.

Will these Partition bullets expand reliably at lower velocities?

Yes. The Nosler Partition is specifically engineered to provide reliable mushrooming across a wide velocity spectrum. The dual-core design and lead-alloy composition ensure consistent expansion even when impact speeds are lower than maximum loads.

How many rounds are in a box?

Each box contains 50 bullets, ready to load into your brass.

What weight retention can I expect?

The Partition design typically retains more than two-thirds of the original bullet weight after expansion, thanks to the rear core being anchored by the integral partition. This retained weight delivers the penetration needed for clean, ethical kills.
