Barnes TSX 458 Caliber 300gr Flat Base Bullets - 20 Count Box

The Barnes TSX 458 Caliber 300gr Flat Base bullets deliver devastating terminal performance for dangerous game hunting. These all-copper hollow point bullets expand reliably while retaining nearly 100% of their weight, creating deep wound channels that stop charging animals in their tracks.

What Makes This Different

Unlike traditional lead-core bullets that fragment and lose mass, the Barnes TSX features a solid copper construction with a hollow point cavity engineered for controlled expansion. The four razor-sharp petals peel back consistently upon impact, doubling the bullet diameter while maintaining structural integrity. This design produces wound channels 30-40% larger than conventional bullets while penetrating deeper through heavy bone and muscle.

Key Features

• All-copper construction retains 95-100% weight for maximum penetration
• Hollow point design creates four cutting petals upon expansion
• 300-grain weight provides optimal sectional density for 458 caliber rifles
• Flat base design ensures consistent seating and reliable feeding
• Lead-free construction meets hunting regulations in all states
• Precision-machined grooves reduce barrel fouling and pressure
• Compatible with standard 458 Winchester Magnum and similar cartridges

Field testing demonstrates these bullets maintain their trajectory accuracy while delivering devastating terminal ballistics on large game. The copper construction eliminates lead contamination concerns for meat hunters while providing the deep penetration required for cape buffalo, elephant, and other dangerous African game. Multiple rings machined into the bullet shank reduce copper fouling typically associated with solid copper projectiles.
