Barnes TSX Bullets .458 cal .458" 450 gr FB 20/ct

Barnes TSX Bullets .458 caliber 450 grain flat base ammunition delivers precision-engineered projectiles engineered for deep penetration and controlled expansion in large-game and dangerous-game hunting applications. Built from 100 percent copper construction, these bullets are designed to expand on impact into four razor-sharp petals while retaining 100 percent of original weight—critical performance characteristics for terminal ballistics consistency across varied shot angles and distances.

The .458" 450 grain specification provides optimal sectional density and velocity retention for the .458 Winchester Magnum and similar large-bore rifle platforms. The flat base design ensures reliable feeding and consistent seating in standardized reloading equipment. Triple-Shock X bullet construction penetrates dense bone and tissue structure while the petaling design creates multiple wound channels, addressing the performance demands of hunters requiring assured one-shot stops on large, heavily built game where marginal hits remain a field reality.

Serious handloaders and dangerous-game hunters operating in African and North American big-game contexts depend on Barnes TSX ammunition for consistency in ballistic tables and reloading data. The 450 grain weight class operates within established .458 Winchester Magnum load parameters, allowing shooters to leverage published load data without custom development. Each 20-round count box contains uniformly manufactured projectiles suited for precision rifle work where component quality directly influences field performance and recovery rates on challenging game.
