The Barnes TSX .405 caliber rifle bullet is a premium all-copper projectile engineered for hunters pursuing big game where penetration and reliability matter. At 300 grains with a .411" diameter, these solid-copper rounds are built to deliver consistent, deep-driving performance on dense bone and heavy muscle tissue—exactly what you need when hunting large North American game or dangerous African species where a first-shot stop is essential.
What sets the TSX apart is its controlled-expansion design. Upon impact, the bullet deploys four razor-sharp cutting petals that create a massive wound channel while the solid-copper construction ensures the round retains 100 percent of its original weight throughout the penetration process. This weight retention translates to deeper, straighter wound tracks and more reliable energy transfer than conventional bullets that fragment or shed material mid-impact.
Each box contains 50 rounds, giving you plenty of ammunition for load development and hunting season. Barnes TSX bullets are a proven choice for reloaders who demand accuracy and terminal performance in equal measure. For best results in your rifle, seat these rounds 0.03 to 0.07 inches off the lands, depending on your specific firearm and chamber dimensions—always start conservative and work up under safe conditions.
