Nosler Trophy Grade 300 Win Mag 180 Grain Partition Ammo - 20 Rounds

The Nosler Trophy Grade 300 Win Mag 180 Grain Partition Ammo delivers the controlled expansion and reliable performance that serious hunters depend on when the shot matters. Built on Nosler Custom brass and loaded to strict tolerances, each round is hand-inspected before boxing—the kind of quality control that separates trophy-grade ammunition from run-of-the-mill loads. The 180-grain Partition bullet is the star here: its tapered jacket initiates expansion instantly on impact while the integral partition anchors the mushroom and preserves the rear core, resulting in consistent penetration whether you're taking a close shot or stretching it across a canyon.

If you hunt elk, moose, or other big game at distance, this round delivers the velocity and energy needed to get the job done. At 2950 fps and 3477 ft-lbs of muzzle energy, it's built for the ballistic demands of the 300 Win Mag platform. The Partition design works across a broad velocity range—you'll get clean expansion at typical hunting speeds without the jacket failures that plague cheaper ammunition under variable conditions. Whether conditions are mild or severe, this bullet curls the jacket uniformly and retains weight where it counts.

Twenty rounds per box means you can train, verify your zero, and hunt with ammunition you trust. Nosler's reputation rests on ammunition that performs in the field, and Trophy Grade is where precision handloading standards meet production-run consistency. This is ammo built for hunters who refuse to compromise on the ammunition that closes the distance between rifle and target.

Frequently Asked Questions

What is a Partition bullet and why does it matter for hunting?

The Partition design uses an integral wall inside the bullet to separate the front and rear lead cores. The front expands rapidly for energy transfer and wound channel, while the partition anchors the expanded mushroom and preserves the rear core for reliable penetration. This two-stage performance makes Partition bullets dependable across a wide range of impact velocities and game sizes.

Is this ammunition suitable for long-range hunting?

Yes. The 300 Win Mag is a popular long-range hunting cartridge, and the 180-grain Partition load delivers the velocity and energy needed for extended-distance work on big game. However, actual effective range depends on your rifle, optics, and shooting skill—use a ballistic calculator to determine your personal limits.

Nosler Trophy Grade ammunition is loaded with Nosler Custom brass, which is designed for handloading. Once you've fired the rounds, the brass can be cleaned, resized, and reloaded according to established reloading protocols for the 300 Win Mag.
