Hornady Superformance CX .300 Win Mag 165gr Lead-Free 20pk
The Hornady Superformance CX in .300 Win Mag 165gr is a lead-free centre-fire rifle cartridge built around Hornady’s monolithic CX (Copper eXpanding) bullet. The CX bullet is machined from copper alloy with a polymer tip that initiates rapid, controlled expansion on impact, while the boat-tail base and secant ogive profile aid in-flight stability and long-range accuracy. Superformance propellant technology drives the 165gr projectile at velocities up to 100–200 fps faster than conventional loads without additional pressure, delivering a flatter trajectory and retained energy at distance. Weight retention typically exceeds 95%, making this round well suited to deer stalking and woodland shooting where shot placement and terminal performance are critical. Brass-cased and boxer-primed, the cartridge is designed for consistent performance and reliability in field conditions.

Frank Forsyth –
Used this round for deer stalking in the woods. The flat trajectory and consistent expansion made it easy to place shots accurately. No lead contamination, which is a big plus for ethical hunting.
Olivia Gray –
Felt a noticeable improvement in shot consistency compared to my previous ammunition. The copper bullet expanded predictably and performed well at 300 yards. Good for woodland use.
Maria Ball –
Highly satisfied with the performance. The velocity is slightly higher than standard loads, and the bullet retained most of its weight. Great for precision shooting in dense cover.
Rebecca Lawrence –
The packaging was secure and the 20 rounds were well organized. Shot a few targets at range and saw excellent accuracy. No issues with feeding or reliability in my rifle.
