Frequently Asked Questions
What makes the CX bullet different from a standard cup-and-core bullet?
The Hornady CX (Copper Alloy eXpanding) bullet is a monolithic copper-alloy projectile with a polymer tip and a series of relief grooves that reduce bore friction and fouling. Unlike traditional cup-and-core bullets, the CX retains over 95% of its original weight upon impact, delivers controlled, uniform expansion across a wide range of velocities, and penetrates deeply through bone and muscle — making it an exceptional choice for large or tough-bodied big game.
Is this ammunition compatible with my .308 Win rifle, including semi-automatic platforms?
Yes. Hornady Superformance .308 Win 165 Gr CX is loaded to SAAMI-standard chamber pressures, making it compatible with any rifle chambered in .308 Winchester — including bolt-action hunting rifles and semi-automatic platforms such as the AR-10. The Superformance propellant achieves its higher velocities through propellant efficiency, not increased pressure, so cycling and reliability are not negatively impacted.
Is this lead-free ammunition California-compliant for hunting?
Yes. The Hornady CX bullet is a lead-free, all-copper-alloy projectile, which qualifies it for use in California's condor zones and other areas where lead-free ammunition is mandated for hunting. Always verify current California Department of Fish and Wildlife regulations for your specific hunting zone before heading afield.
