Barnes TSX Bullets .458 cal .458" 350 gr FB 20/ct

The Barnes TSX Bullets .458 caliber 350 grain flat-base projectiles deliver exceptional stopping power and barrier penetration for large-game hunting and specialized rifle applications. Engineered from 100-percent copper construction, these solid-copper rounds expand predictably on impact while retaining full original weight—a critical advantage when penetrating dense bone and heavy tissue encountered in big-game scenarios.

The TSX design creates four razor-sharp copper petals upon impact, generating a broad frontal surface area that maximizes energy transfer while maintaining deep, straight-line penetration through vitals. The 350-grain mass in .458 diameter delivers the momentum required for .458 Winchester Magnum and .458 SOCOM platforms to achieve consistent performance at extended ranges. The flat-base configuration enhances ballistic stability and aids in magazine feeding. Each 20-count box provides shooters with match-grade ammunition for sight-in, practice, and field deployment.

Serious hunters and rifle operators pursuing elk, moose, African game, and dangerous-game scenarios depend on Barnes TSX ammunition for its documented track record of one-shot stops. Reloaders and shooters building custom .458 loads value the weight consistency and dimensional precision TSX bullets provide. The 100-percent copper construction also delivers reduced barrel fouling compared to traditional lead-core alternatives, extending barrel life during intensive training or field use.

Barnes Triple-Shock X bullets represent the engineering standard for modern solid-copper rifle projectiles. The .458/350gr combination addresses the specific ballistic window where larger-bore rifles operate—combining velocity constraints with the heavy, slow-moving projectile design that maximizes tissue destruction and bone-breaking capability in premium hunting and specialized tactical applications.
