Barnes TSX Bullets .270 cal .277" 150 gr FB 50/ct

Barnes TSX Bullets .270 cal .277" 150 gr FB are purpose-built projectiles engineered for hunters and precision shooters who demand consistent, ethical one-shot performance. Designed for the .270 Winchester cartridge, these all-copper hollow-point rounds deliver the terminal performance required for medium to large game at extended ranges. Available in convenient 50-round boxes, Barnes TSX ammunition has become the standard among serious hunters and tactical riflemen who prioritize reliability and deep penetration.

The 150-grain TSX (Triple-Shock X) projectile is constructed from 100 percent copper, eliminating the lead core that characterizes traditional jacketed bullets. Upon impact, the TSX expands in a controlled manner, creating four razor-sharp petals with substantial cutting diameter while maintaining deep, straight-line penetration through heavy bone and muscle. The flat-base design (FB) optimizes ballistic stability and velocity retention downrange, making these rounds exceptionally accurate at distance. This controlled-expansion architecture ensures energy transfer is maximized without fragmentation, preserving meat quality and delivering consistent terminal performance across varying impact velocities.

Reloaders and factory ammunition builders alike specify Barnes TSX bullets for .270 Winchester applications ranging from hunting elk and mule deer to precision rifle competitions. The .277" diameter matches standard .270 Winchester bore specifications, ensuring optimal fit and accuracy in modern and vintage rifles. These bullets perform best when loaded to published Barnes specifications and fired through properly maintained rifled bores; they are not recommended for smoothbore firearms. Whether you are handloading precision rounds or evaluating premium factory ammunition, the Barnes TSX 150-grain delivers the terminal performance and accuracy that separates ethical, effective shooting from marginal results.
