KFF Defense presents the Weatherby Select Plus series, specifically engineered for applications demanding robust terminal performance. This particular loading integrates the potent 378 Weatherby Magnum cartridge with the advanced 270-grain Barnes TSX Lead Free projectile, designed for consistent ballistics and significant energy transfer.
Key Features
Optimized Cartridge Design
The 378 Weatherby Magnum cartridge is inherently designed for high muzzle velocity and substantial downrange kinetic energy, enabling a flat trajectory crucial for extended engagement distances. This design principle facilitates rapid energy delivery upon impact, supporting effective incapacitation.
Barnes TSX Lead Free Projectile
This ammunition features the 270-grain Barnes TSX (Triple-Shock X-Bullet), an all-copper, monolithic lead-free projectile. The TSX is engineered for controlled, four-petal expansion across a broad velocity range, ensuring deep penetration and near 100% weight retention. This construction minimizes fragmentation while maximizing energy transfer within the target, making it a reliable choice for ethical take-down and compliant with lead-free hunting regulations where applicable.
Precision Manufacturing
Weatherby Select Plus ammunition undergoes rigorous manufacturing processes to ensure component consistency. This includes precise powder charges, uniform primer seating, and consistent case dimensions, all contributing to reliable ignition, predictable ballistic performance, and repeatable accuracy necessary for critical shots.
