Weatherby Ammunition remains true to the concept Roy developed in the 1940s. At the same time, our ammunition also takes advantage of the latest in controlled expansion bullets which are capable of harnessing the higher velocities to create a cartridge that provides the ultimate in penetration, large wound channels and more one-shot kills. Nothing shoots flatter, hits harder or is more accurate.FeaturesA polymer tip resists deformation in the magazine and initiates expansion upon impactFully tapered alloy jacket is bonded to the special lead alloy core through a proprietary process designed for controlled expansion, deep penetration and 60 – 70% weight retentionTotally concentric impact extruded jacket bonds completely to the bullet core for extreme accuracyBallistically engineered, the solid base boat tail acts as a platform for large diameter mushroom and prevents bullet deformation during firing
