Nosler Partition 30 Cal 150gr Spitzer Bullets - Box of 50

The Nosler Partition 30 Cal 150gr Spitzer Bullets are the reloader's choice for building hunting ammunition that delivers consistent, lethal performance in the field. Since 1948, the Partition design has been the gold standard for hunters demanding deep penetration, massive energy transfer, and reliable bullet performance across a wide range of hunting scenarios and impact velocities. This box of 50 bullets gives you the components to load ammunition tailored to your rifle and hunting conditions.

What sets the Partition apart is its dual-core construction and integral partition wall. The front lead core expands rapidly on impact to create a devastating wound channel, while the rear core—held in place by the partition—resists deformation and retains over two-thirds of the original bullet weight for deep, straight-line penetration. This separation of function means you get both the shock and energy dump of rapid expansion and the penetration needed to reach vital organs on larger game or at longer distances.

The tapered copper-alloy jacket is engineered to rupture instantly at the thin nose section, yet thicken progressively toward the base. This design maintains controlled expansion at all practical impact velocities, from close-range encounters to moderate long-range shots. The jacket curls uniformly outward regardless of impact speed, giving you predictable terminal performance whether you're hunting in thick cover or across open country. Nosler's special crimp locks on each bullet add structural rigidity, resisting deformation during the reloading process—especially valuable when loading for magnum cartridges or when using heavy powder charges.

Reloaders appreciate the Partition for its consistent length, weight, and ogive design, which translate to reliable bullet seating and predictable ballistic behavior. Whether you're developing loads for a 30-06, .308 Winchester, or magnum cartridge in .30 caliber, these 150-grain bullets give you the foundation for ammunition you can trust in the field.

Frequently Asked Questions

What calibers and cartridges can I load these 30 caliber bullets into?

The Nosler Partition 30 Cal (.308”) 150gr bullets are compatible with any .30 caliber rifle cartridge, including the .30-06 Springfield, .308 Winchester, .300 Winchester Magnum, .300 Weatherby Magnum, and other .30 caliber rifle rounds. Always consult published reloading data for your specific cartridge and powder combination before loading.

Are these bullets suitable for hunting, and what game are they designed for?

Yes, the Partition is a hunting bullet designed for reliable terminal performance on game animals. The 150-grain weight in .30 caliber is appropriate for medium to large game, including deer, elk, and similar-sized animals, depending on your cartridge velocity and shooting distance. The bullet's controlled expansion and deep penetration make it versatile across a range of hunting conditions.

What does the integral partition do?

The partition is an internal wall that separates the front and rear lead cores. It supports the expanded mushroom of the front core while preventing the rear core from deforming, allowing it to retain over two-thirds of the bullet's original weight. This design delivers both the immediate shock and energy transfer of the expanding front core and the deep, reliable penetration of the retained rear core.
