Hornady's Custom ammunition, including rounds with the CX (Copper alloy eXpanding) bullet, undergoes rigorous inspection to meet high-quality standards. The CX bullet, constructed from a monolithic copper alloy, is a top-tier hunting projectile designed for maximum range, accuracy, and deep penetration. It features a heat-resistant polymer tip for consistent aerodynamic performance and high ballistic coefficients across the bullet's trajectory. The grooves on the bullet reduce bearing surface and fouling.
