The Nosler Partition 338 Cal 225 Grain Spitzer bullets are a reloader's go-to for medium to large game hunting. Built on over 75 years of hunting bullet innovation, the Partition design combines controlled expansion with deep penetration—two qualities that matter when the shot counts. The 225-grain spitzer profile delivers the ballistic coefficient hunters expect from a .338 caliber round, whether you're loading for .338 Winchester Magnum, .338 Lapua Magnum, or another .338 platform.

What sets the Partition apart is its dual-core construction. The front core mushrooms on impact, creating the shock needed for a quick, ethical kill. A copper partition between the cores then does the heavy lifting: it supports the expanded mushroom while keeping the rear core mostly intact. This design retains roughly two-thirds of the original bullet weight, ensuring penetration even on angled shots or after passing through heavy bone and muscle. Nosler's tapered copper-alloy jacket ruptures cleanly and uniformly, minimizing fragmentation and maximizing energy transfer where it counts.

Reloaders trust the Partition because it performs across a range of velocities. Whether you're loading a hot magnum load or a more conservative hunting round, the dual-core geometry and lead-alloy composition deliver consistent mushrooming. Each box contains 50 bullets, enough for a solid hunting season or serious range testing before the season opens. If you've built a .338 for elk, moose, or long-range precision hunting, the Nosler Partition remains a proven, field-tested choice.
