Specifically engineered for big game and safari hunting applications, Barnes® VOR-TX® Safari .458 Lott 500gr TSX FB ammo offers unmatched destructive power thanks to the straight-tracking and deep penetrating TSX FB bullet design. All-copper bullet construction maximizes weight retention and energy transfer for dependable stopping power hunting targets, while precision-cut rings in the bullet shank act as relief valves, allowing the bullet to expand into the grooves for devastating performance on jungle cats and grassland predators. Further, this ammo boasts clean-burning powders and propellants loaded in premium brass casings for consistent ignition, flat trajectories, and improved muzzle velocities. 20 rounds.
