KFF Defense presents Weatherby .257 Weatherby Magnum 100 grain TTSX ammunition. Roy Weatherby established his legacy on ultra-high velocity magnum cartridges in the 1940s. This commitment to superior ballistic performance remains foundational to current Weatherby ammunition production. These cartridges are designed to deliver a flat trajectory, substantial kinetic energy transfer, and consistent accuracy.
Key Features
Performance Profile
The .257 Weatherby Magnum cartridge is engineered for exceptional velocity, enabling reduced bullet drop at extended ranges. This ammunition is loaded to maximize the inherent ballistic advantages of the .257 WBY Mag, optimizing for high-energy impact and efficient terminal performance across varied conditions.
Bullet Construction
Utilizing the Barnes 100 grain Triple-Shock X-Bullet (TTSX), this load provides reliable expansion and deep penetration without lead fragmentation. The all-copper, monolithic construction ensures high weight retention and consistent performance across a broad velocity spectrum, mitigating jacket/core separation and enhancing ethical harvest capabilities.
Manufacturing Integrity
Weatherby’s production standards enforce stringent quality control, ensuring lot-to-lot consistency in propellant charges, primer seating, and case dimensions. This meticulous attention to detail is critical for maintaining the tight groups and repeatable ballistics expected from a premium magnum hunting cartridge.
