Nosler Partition 270 Cal 150 Grain Spitzer Bullets - Box of 50

Nosler Partition 270 caliber 150 grain spitzer bullets are among the most trusted rifle bullets for hunting, built on a design that's proven itself in the field for decades. Each box contains 50 rounds of .277" diameter bullets with a flat base, engineered for the kind of terminal performance—expansion, penetration, and weight retention—that serious hunters depend on when the shot counts. If you reload for .270 Winchester or similar cartridges and want bullets that deliver consistent, predictable results across a range of velocities, these are worth your consideration.

The Partition design is the foundation of Nosler's reputation: a front lead core that expands on impact and a rear core housed behind an integral partition wall. That partition does the real work—it supports the expanded mushroom and keeps the back half of the bullet intact for deep, bone-crushing penetration. The result is a bullet that sheds energy where it should, maintains structural integrity through heavy bone, and typically retains more than two-thirds of its original weight.

Construction details matter in reloading. The fully tapered copper-alloy jacket ruptures instantly at the thin mouth yet thickens gradually along the shank, controlling expansion at both high and low impact velocities. Nosler's dual lead-alloy cores work together to support reliable mushrooming. The 150 grain weight is a versatile choice for .270 hunting, balancing velocity retention and energy delivery across common hunting ranges and game sizes.

Whether you're loading for whitetail, mule deer, or elk, Nosler Partition bullets reward attention to load development with repeatable, lethal performance. Buy this 50-round box as a single unit or stock up for the season.
