Barnes TSX 458 Caliber 500gr Flat Base Bullets - 20 Count Box

The Barnes TSX 458 caliber 500-grain flat base bullets deliver exceptional terminal performance for dangerous game hunting and long-range precision shooting. These triple-shock X bullets feature Barnes' proven all-copper construction that ensures maximum weight retention and devastating expansion on impact.

What Makes This Different

Unlike traditional lead-core bullets that can fragment and lose mass, the TSX design maintains 99% of its original weight through complete penetration. The all-copper construction eliminates lead contamination concerns while providing superior ballistic coefficients compared to standard cup-and-core designs. Four razor-sharp cutting petals create massive wound channels while the solid copper shank drives deep for reliable organ penetration.
