Federal Premium Ammunition 300 Winchester Magnum 180 Grain Nosler Partition 20RD

Federal Premium 300 Win Mag 180 Grain Nosler Partition ammo delivers the controlled expansion and deep penetration that big-game hunters need. Built on the proven Nosler Partition bullet design, this load combines immediate energy transfer on impact with the skeletal integrity to drive through heavy bone and muscle. Whether you're chasing elk across ridgelines, taking a long-range shot at a mule deer, or hunting moose in tough country, this 300 Winchester Magnum loading is engineered to perform when it counts. You get 20 rounds per box—enough for practice, scouting, and season prep before heading afield.

The Nosler Partition bullet is purpose-built for larger game animals. The forward half mushrooms immediately on contact, initiating rapid energy transfer that stops the target quickly. The rear half, separated by a copper partition, remains intact and drives deep. This two-stage design means you get both the shock of a rapid-expanding bullet and the penetration of a solid core—a combination that translates to ethical, effective shots even at extended ranges or challenging angles.

Federal Premium ammunition is loaded to strict tolerances and uses quality brass and primers, giving you the consistency and reliability that serious hunters expect. The 300 Win Mag is one of North America's most effective long-range hunting cartridges, and pairing it with a proven bullet like the Nosler Partition makes this load a dependable choice for your hunt.
