Barnes .458 Caliber 300 Grain TSX Flat Base Bullets – 20 Count

Barnes .458 Caliber 300 Grain TSX Flat Base bullets are all-copper component projectiles built around Barnes’ Triple-Shock X design. MPN 30615 identifies the 300-grain TSX Flat Base configuration supplied 20 bullets per box.

The TSX uses monolithic copper construction and multiple engineered grooves in the bullet shank. These grooves reduce bearing surface, pressure and copper fouling while supporting accuracy, controlled expansion, penetration and weight retention.

The 300-grain projectile uses a flat-base profile and has a .458-inch bullet diameter.

These are component bullets intended for metallic cartridge reloading and are not loaded ammunition. Each box contains 20 projectiles.
