Wby Ammo 7mmwby 154gr Hdy 20/200

Weatherby 7mm Weatherby Magnum 154-grain ammunition delivers the ultra-high velocity performance that defined the Weatherby brand since Roy Weatherby's groundbreaking work in the 1940s. This 20-round box fires Hornady Interlock projectiles at 3,260 feet per second, combining flat trajectory with hard-hitting terminal ballistics that serious hunters and precision shooters demand from a magnum cartridge.

The 154-grain bullet weight sits at the optimal balance for 7mm Weatherby Magnum applications—heavy enough to carry energy downrange without sacrificing the velocity advantage that magnums are engineered to deliver. At 3,260 fps, this load generates significantly flatter trajectory than standard .7mm caliber offerings, reducing holdover calculations at extended ranges. The Hornady Interlock projectile is designed for progressive expansion, maximizing energy transfer while maintaining structural integrity through heavy bone and muscle.

This ammunition serves hunters pursuing medium to large game at distance, as well as precision rifle competitors who rely on Weatherby's velocity advantage for tight shot groups and reliable performance. The 20-round per box configuration is standard for magnum rifle ammunition and makes it practical for practice sessions, load development, and field use. When fired from a Weatherby rifle chambered in 7mm Weatherby Magnum, this ammunition delivers the accuracy and downrange energy the platform was designed to achieve.
