Nosler Trophy Grade ammunition in .338 Winchester Magnum (brand part no. 61058) loads a 210-grain Partition bullet, the design that put Nosler on the map, built for hunters who want proven, controlled-expansion performance and a flatter trajectory. Trophy Grade is high-quality, production-run ammunition manufactured to strict tolerances and hand-packaged, using Nosler Custom brass throughout. The Partition’s fully tapered jacket ruptures instantly at the thin jacket mouth, while the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at both high and low velocities, and the integral partition wall retains the rear lead-alloy core. For .338 Win Mag hunters who want that classic controlled-expansion performance at a flatter trajectory, this rifle ammunition is built for the hunt.

Frequently Asked Questions

How does the Partition’s integral wall work? A jacket wall splits the bullet into front and rear cores; the front expands into a mushroom while the wall holds the rear core intact for continued penetration.

Why choose the lighter 210gr loading? The lighter weight trades a little mass for extra velocity and a flatter trajectory, while keeping the same proven Partition construction.
