The 28 Nosler Trophy Grade cartridge from Nosler pairs a flat-shooting magnum case with the time-tested Partition bullet — a 160-grain jacketed soft point built around a dual-core design that delivers controlled expansion and deep penetration on heavy game. Engineered for hunters who need reliable terminal performance at ranges where lesser projectiles fold, this load maintains its structural integrity through shoulder blades and heavy bone. The 28 Nosler is a high-velocity magnum designed to flatten trajectory and deliver energy downrange — expect velocities that keep the bullet supersonic well past distances where most hunting cartridges lose stability. Each round is hand-inspected during packaging, loaded into reloadable brass cases with non-corrosive Boxer primers.
Built for the Box
The Partition bullet features a fully tapered jacket that ruptures instantly at the thin mouth on impact, while progressive thickening along the shank controls expansion uniformly at velocities ranging from moderate to magnum. An integral partition wall separates the front core — which mushrooms and sheds energy — from the rear core, which remains intact to drive penetration. The rear core is locked in place by a special crimp, preventing deformation under the pressure of heavy magnum charges. The result: a bullet that retains over 60% of its original weight even after passing through heavy tissue and bone, with a sectional density of 0.283 and a G1 ballistic coefficient of 0.475 for predictable drop and drift compensation.

The 28 Nosler cartridge operates at magnum pressures, delivering velocities that extend effective hunting range on elk, moose, and bear. This load is optimized for rifles with 24-inch or longer barrels to maximize velocity and ballistic efficiency. For more magnum hunting loads, see our full 28 Nosler ammo selection.
