Hornady 243 Cal 6mm 80gr CX

The Hornady 243 Cal 6mm 80gr CX is a precision-engineered monolithic bullet component crafted for handloaders seeking lead-free construction, controlled expansion, and long-range performance in 6mm-caliber rifles. Weighing 80 gr with a .243-inch diameter, the 243 Cal 6mm 80gr CX utilizes Hornady’s Copper eXpanding (CX) all-copper alloy design to retain over 95% of its mass and deliver consistent terminal results on varmint and medium game such as pronghorn, coyotes, and deer.

The streamlined profile of the 243 Cal 6mm 80gr CX features a Heat Shield® polymer tip, secant ogive, and boat-tail base—delivering a high ballistic coefficient for flat trajectory and minimal wind drift. When propelled between 3,000 and 3,200 fps in cartridges like .243 Winchester, 6mm Creedmoor, or 6mm ARC, the 243 Cal 6mm 80gr CX retains velocity and offers tight groupings out to 600 yards.

Constructed as a single-piece copper bullet, the 243 Cal 6mm 80gr CX resists jacket-core separation and fragmentation, ensuring clean wound channels and reliable penetration. Hunters and varmint shooters appreciate that the 243 Cal 6mm 80gr CX offers ethical terminal performance—even in backstop-sensitive environments. Its monolithic design results in minimal lead fouling, making it ideal for use in states with lead restrictions.

Stabilizing effectively in barrels with typical twist rates of 1:7 to 1:8, the 243 Cal 6mm 80gr CX feeds reliably in bolt-action, AR-platform, and magazine rifles. Its concentric jacket and polished ogive support consistent seating depth and repeatable point-of-impact. Handloaders value the 243 Cal 6mm 80gr CX for its smooth cycling and reliable accuracy across varied powders and primers.

Manufactured at Hornady’s Grand Island, Nebraska facility, the Hornady 243 Cal 6mm 80gr CX is sold strictly as a bullet component and requires compatible brass, powder, and primers. With meticulous quality control over tip alignment, weight uniformity, and jacket concentricity, the 243 Cal 6mm 80gr CX stands as an elite lead-free option for shooters seeking long-range precision, flat-shooting trajectory, and ethical terminal performance in the 6mm-class category.
