The Nosler Trophy Grade 300 Winchester Magnum 200 grain Partition ammunition is purpose-built for hunters who demand a bullet that performs the same way in the field every time. The Partition design—the benchmark for hunting rounds since 1948—splits its structure into two cores separated by Nosler's integral partition. The front core expands rapidly on impact to transfer energy and create a wound channel, while the rear core stays intact, giving you deep penetration and retained weight for ethical, reliable kills on medium to large game.
Nosler loads these rounds into premium brass, meaning you're getting ammunition built to the same exacting standards that made the Partition bullet a legend. The 200-grain weight in the 300 Win Mag hits that sweet spot for velocity and energy at extended range, making it a favorite for long-range hunting applications where you need both power and accuracy. Whether you're hunting elk in high country or taking a long-range shot at mule deer, this ammunition delivers the terminal performance hunters have trusted for decades.
Every box of Nosler Trophy Grade comes with 20 rounds, so you get consistent ammunition for your hunting season without compromise. If reliability matters to you—and it should when your shot counts—this is ammunition you can count on.

The 200 grain Partition is suitable for medium to large game hunting. The bullet's design provides the penetration and energy retention needed for reliable performance on elk, deer, and similar-sized game at extended ranges.
The Partition splits into two cores separated by an integral barrier. The front core expands on impact to create immediate wound trauma, while the rear core remains intact and protected by the partition, ensuring deep penetration and retaining more than two-thirds of the original bullet weight.
Nosler Trophy Grade ammunition is loaded in premium Nosler brass, which is suitable for reloading after firing, though reloading components and processes are separate from the factory load.
Nosler Trophy Grade 300 Winchester Magnum ammunition comes in boxes of 20 rounds.
