Hornady Superformance 300 Win Mag 165gr CX Copper Expanding Ammo

The Hornady Superformance 300 Winchester Magnum ammunition delivers premium copper alloy expanding performance with increased velocity over conventional loads. This lead-free hunting ammunition combines Hornady's proprietary powder technology with CX (Copper alloy eXpanding) bullets for deep penetration and controlled expansion.

What Makes This Different

Superformance technology increases velocity up to 200 fps over standard ammunition without increased chamber pressure or barrel wear. The monolithic copper construction ensures 95% weight retention while creating devastating wound channels. Unlike traditional lead-core bullets, the CX design maintains structural integrity through bone and heavy muscle tissue.

Key Features

• 165-grain CX copper alloy expanding bullet for maximum penetration
• Superformance powder technology increases velocity without pressure spikes
• Lead-free construction meets all hunting regulations
• Polymer tip initiates rapid expansion at impact velocities
• Monolithic design retains 95% of original weight

This ammunition excels in long-range hunting scenarios where energy retention and accuracy matter most. The 165-grain bullet weight provides optimal balance between velocity and momentum for medium to large game hunting. Copper construction eliminates lead fouling while maintaining consistent accuracy across temperature variations.
