Frequently Asked Questions
What makes the CX bullet different from Hornady's SST or InterBond bullets?
The CX (Copper Alloy eXpanding) bullet is a monolithic copper-alloy projectile, meaning it has no lead core. This construction delivers over 95% weight retention and deep, straight-line penetration even through heavy bone. Unlike bonded lead-core bullets like the InterBond, the CX is lead-free and maintains its shape more reliably under high-velocity impact, making it particularly effective on large or tough-skinned game.
Is this Hornady 300 Win Mag ammo safe to use in any 300 Win Mag chambered rifle?
Yes. Hornady Superformance ammunition is loaded to SAAMI-standard pressures and is safe for use in any firearm chambered in 300 Winchester Magnum in good working condition. The Superformance velocity gains come from optimized progressive propellants, not elevated pressure, so there is no additional stress on your action or barrel compared to standard 300 Win Mag loads.
How does this load perform at longer hunting ranges compared to standard 300 Win Mag ammo?
The additional 100–200 fps from the Superformance propellant keeps the 165 gr CX bullet flatter and retains more energy at distance. At 400 yards, the higher initial velocity translates to noticeably less drop and greater retained energy compared to conventional 165 gr loads, making it a strong choice for hunters who may encounter shots beyond 300 yards in open terrain.
