Barnes TSX Bullets .458 caliber 300 grain full body (FB) rounds are purpose-built monolithic copper projectiles engineered for controlled expansion and maximum weight retention on impact. Each 20-count box delivers ammunition-grade components trusted by hunters and shooters who demand reliable terminal performance in large-caliber applications.
The TSX design features a 100-percent copper construction with four razor-sharp petals that deploy upon impact. At 300 grains in .458-inch diameter, these bullets penetrate dense bone and heavy tissue while maintaining structural integrity throughout the wound channel. The full body configuration eliminates the traditional lead core, ensuring the projectile retains 100 percent of its original weight—a critical factor for consistent ballistics and predictable deep penetration in large game scenarios. This weight retention directly translates to greater energy transfer downrange and reliable performance across varying distance and velocity combinations typical of .458 caliber rifles.
Shooters pursuing large dangerous game, including African and North American big game at extended ranges, rely on .458 caliber ammunition for its stopping power and barrier-penetrating capability. The Barnes TSX 300-grain bullet addresses the specific demands of rifles chambered in .458 Winchester Magnum, .458 Lott, and other .458-inch bore cartridges. Component shooters and ammunition reloaders use TSX projectiles to assemble rounds tailored to their exact rifle specifications and hunting conditions. The 20-round per box quantity supports both practice at the range and field applications.
Barnes Bullets remains the industry standard for solid-copper monolithic projectiles, with proven performance across multiple caliber platforms. The TSX line represents decades of terminal ballistics research and field validation, making it a baseline choice for hunters who prioritize one-shot effectiveness and deep, reliable penetration in premium cartridge applications.
