Barnes Triple-Shock X (TSX) Bullets in .404 Caliber, .423-Inch, 400-Grain Flat Base (part no. 30537) give dangerous-game rifle handloaders a solid-copper bullet built for deep, straight-line penetration. Barnes machines the TSX from 100 percent copper with no lead core, so the bullet expands into four razor-sharp petals while retaining the vast majority of its original weight. Each box holds 50 bullets built for big-game rifle hunting.
