The Nosler Trophy Grade 300 RSAUM 165 Grain Partition Spitzer ammo is a proven match for hunters who demand accuracy and clean, ethical kills on medium-sized game. Built on Nosler's legendary Partition bullet design—the industry standard since 1948—this rifle ammunition pairs a 165-grain spitzer projectile with premium brass to deliver the kind of on-game performance that's made Nosler a hunter's favorite for generations. Whether you're working steel on the range or hunting at distance, Trophy Grade ammo is loaded to exacting standards for consistency and reliability.

At the heart of every round is the Partition bullet, distinguished by its dual-core construction. The front core expands rapidly on impact to create hydrostatic shock and immediate trauma, while an integral partition wall separates and protects the rear core. That design means the back half of the bullet stays intact deep in the vitals, delivering penetration that anchors game and minimizes tracking.

This is serious, field-tested ammunition for hunters who understand that ammunition is not where you compromise. Each box of 20 rounds is loaded with the same precision Nosler applies to their premium hunting components—the same bullets and brass that go into custom hand loads. If your 300 RSAUM is zeroed and ready, Trophy Grade ammo will execute.
