The Nosler Partition 25 caliber 100 grain spitzer bullets have been the go-to choice for serious hunters and handloaders since 1948. If you're building accurate, hard-hitting rifle ammunition for medium game, these bullets deliver the reliable expansion and penetration that made Nosler's name in the hunting world. Each box contains 50 bullets ready to load into your favorite 25 caliber rifle cartridges.
What sets Partition bullets apart is their dual-core construction: a tapered copper-alloy jacket designed to rupture and peel back uniformly on impact, combined with a lead-alloy core split by an internal partition. The front core expands rapidly to create that devastating mushroom effect, while the rear core stays sheltered behind the partition. The result is deeper penetration than fragmenting bullets while still delivering the energy transfer you need for clean, quick kills. The 100 grain weight in this caliber strikes a balance between velocity and retained mass, making it suitable for hunting applications where controlled expansion matters.
Reloaders appreciate Partition bullets for their consistent quality and predictable performance across a wide velocity range. The spitzer profile delivers better ballistics than round-nose designs, so your handloads will shoot flatter and maintain energy downrange. Whether you're loading for a varmint rifle, a classic hunting cartridge, or something in between, these bullets give you the platform to build ammunition that performs when it counts.
| Caliber | 25 |
| Weight | 100 grains |
| Bullet Type | Spitzer |
| Count per Box | 50 |
| Core Design | Dual-core with integral partition |
| Jacket Material | Copper-alloy |
These are 25 caliber bullets, so they're designed for cartridges in the .25 bore diameter family. Common examples include the .25-06 Remington, .25 WSSM, and other .25 caliber rifle cartridges. Always verify your specific cartridge's reloading data before loading, as powder charges and seating depths vary by cartridge.
The dual-core partition design is engineered to deliver controlled expansion paired with deep penetration. The front core mushrooms for initial impact trauma while the rear core—protected by the partition—remains intact and drives deep into the animal. This differs from solid copper bullets, which shed weight, or traditional soft-point designs that may over-expand or fragment depending on impact velocity.
Each box contains 50 Nosler Partition 25 caliber 100 grain spitzer bullets ready for reloading. These are components only; you'll need to source brass, powder, and primers separately to complete your ammunition.
Nosler Partition bullets are designed to perform across a wide velocity range, which means they deliver consistent expansion whether fired at close range or extended distance. The 100 grain weight in 25 caliber is engineered to mushroom reliably at velocities typical of medium-game hunting applications.
