Nosler Trophy Grade 300 Win Mag 200 Grain Partition Ammo

Nosler Trophy Grade 300 Winchester Magnum 200 Grain Partition ammunition is a premium hunting load designed for elk, moose, and other large game. Each cartridge combines a heavy 200 grain Nosler Partition projectile with Nosler Premium Brass for hunters looking for a purpose-built big-game load.

Nosler lists this load at a muzzle velocity of 2,750 FPS and muzzle energy of 3,357 ft-lbs. Each factory box contains 20 rounds and is manufactured in the United States.

200 Grain Nosler Partition Bullet

The Nosler Partition uses the company’s distinctive dual-core construction. An integral copper-alloy partition separates the front and rear lead cores, allowing each section of the projectile to perform a different role after impact.

The front core is designed to expand rapidly, while the integral partition supports the expanded front section and protects the enclosed rear core. According to Nosler, this construction allows the bullet to retain more than two-thirds of its original weight while supporting the deep penetration needed for large game.

Built for Elk & Moose Sized Game

This Trophy Grade load is specifically identified by Nosler for elk and moose sized game. The combination of a 200 grain Partition projectile and the 300 Winchester Magnum cartridge makes it a purpose-built option for hunters pursuing larger-bodied animals.

Nosler Premium Brass

Each cartridge is loaded using Nosler Premium Brass. Combined with the company’s Partition hunting projectile, this gives hunters a complete factory-loaded cartridge built around Nosler components rather than a general-purpose rifle load.

2,750 FPS Muzzle Velocity

Nosler lists this 200 grain 300 Win Mag load at 2,750 FPS at the muzzle, producing 3,357 ft-lbs of muzzle energy. Published test data was obtained using a 24-inch barrel with a 1:10 twist rate. Actual velocity and trajectory can vary depending on the firearm, barrel, atmospheric conditions, and other factors.
