Wby Ammo 7mmwby 160gr Nos Prt 20/200

Weatherby 7mm Wby Magnum 160 Grain Nosler Partition ammunition represents the core performance philosophy that Roy Weatherby established in the 1940s: ultra-high velocity magnum loads engineered for flat trajectories, deep penetration, and consistent accuracy. This cartridge delivers the speed and impact energy demanded by serious hunters and long-range shooters pursuing medium to large game across extended distances.

The 160-grain Nosler Partition bullet is the critical component here. This bonded-core design separates into two distinct sections—a soft front core for rapid expansion upon impact, and a heavy rear core for deep penetration and weight retention. That dual-purpose construction matters in the field: it generates reliable expansion at the high velocities Weatherby ammunition achieves, while the retained weight ensures the bullet carries sufficient momentum through heavy bone and muscle. The 7mm Wby Magnum case, when loaded to Weatherby factory specifications, drives this bullet to velocities that flatten the shooting curve and reduce wind drift compared to standard 7mm offerings.

This load is purpose-built for hunters working with Weatherby rifles or comparable magnum-capable bolt actions at ranges beyond 200 yards where trajectory and wind performance separate ethical shots from misses. The 20-round per box format provides sufficient ammunition for hunting seasons, sighting-in, and range validation without excess. Shooters accustomed to standard magnum velocities will notice the flatter arc and reduced holdover when transitioning to Weatherby's factory ammunition—a measurable advantage in unpredictable field conditions.
