Federal Premium Vital-Shok Ammunition 243 Winchester 100 Grain Nosler Partition Moly 20RD

Federal Premium Vital-Shok .243 Winchester 100 grain ammunition delivers reliable performance for hunters pursuing medium-sized game. Built around the Nosler Partition bullet—a design proven in the field for controlled expansion and deep penetration—this round pairs controlled energy transfer with the flat-shooting characteristics that make the .243 Winchester a favorite for deer, antelope, and similar-sized animals. The Nosler Partition's dual-core construction means you get the expansion needed for effective energy transfer on impact without sacrificing the penetration that reaches vital zones.

The Nosler Partition bullet design splits the difference between explosive expansion and deep, reliable penetration. The front half of the bullet expands on contact, creating immediate tissue damage, while the rear half remains solid—held by a copper partition—to carry deep into the animal. That combination gives you confidence that your shot will perform consistently, whether you're hunting at close range or stretching it out to medium distances where the .243 Winchester thrives.

Each box contains 20 rounds, so you get plenty for practice, sighting in, and hunting season. Federal Premium ammunition is loaded to strict tolerances and uses quality components throughout, so you can focus on shot placement rather than worrying about reliability. If the .243 Winchester is your rifle, Federal Premium Vital-Shok with the Nosler Partition is a sensible, time-tested choice for game hunting.

How does the Nosler Partition bullet work?

The Nosler Partition features a copper partition inside the bullet that divides it into two sections.
