Federal Premium Ammunition 300 Winchester Short Magnum (WSM) 180 Grain Nosler Partition Box of 20

Federal Premium Ammunition 300 Winchester Short Magnum (WSM) 180 Grain Nosler Partition Box of 20 pairs Federal’s premium case with the Nosler Partition, the bullet that established controlled expansion as a design category over 70 years ago. The bullet’s internal partition wall separates the front expanding section from a solid rear core, guaranteeing weight retention no other design of that era could match. Federal loads this bullet to the full velocity potential of the 300 WSM case.

The Original Controlled-Expansion Design

As a result, hunters who want a proven, decades-tested bullet design often choose this loading over newer alternatives. The front section expands rapidly for a wide wound channel, while the rear core drives on for reliable exit-wound penetration. Meanwhile, Federal maintains tight quality control on every batch it manufactures for this line.

About This Federal Premium Ammunition 300 Winchester Short Magnum (WSM) 180 Grain Nosler Partition Box of 20 Load

Federal built its reputation on pairing proven bullet designs with consistent, accurate cartridge cases. For reference, this loading suits big game hunting rather than target shooting, since premium partition bullets cost more than practice ammunition. Therefore, many hunters pair this loading with a lighter, cheaper round for sighting in.
