Hornady CX (Copper alloy eXpanding) bullets in 7mm .284 diameter 139 grain are a precision-engineered monolithic hunting projectile built for reloaders who want a lead-free 7mm copper solid bullet that drives deep, holds together, and performs reliably on medium to large game at any distance their cartridge can carry.

Special Features
- One-piece copper alloy construction eliminates core-jacket separation, delivering 95 percent or greater weight retention through bone, muscle, and heavy hide on large game animals.
- Heat Shield polymer tip resists aerodynamic heating during flight, preserving a consistent ballistic coefficient from muzzle to target and initiating controlled expansion on impact.
- Optimized groove geometry reduces bearing surface and bore fouling, allowing the bullet to run at lower pressure and leave less copper buildup than traditional flat-band monolithic designs.
- Boattail base reduces base drag and sustains downrange velocity, producing a flatter trajectory with reduced wind drift at extended distances.
- Compatible with any cartridge chambered for a .284 diameter projectile, including 7mm-08 Remington, 7mm Remington Magnum, 7mm PRC, 280 Ackley Improved, 7mm WSM, and 7mm Weatherby Magnum.
- Lead-free construction makes this bullet a nontraditional option well suited for areas and applications that require non-lead projectiles.
Practical Benefits
- The 139 grain weight gives you a versatile bullet that balances velocity and momentum across a wide range of 7mm cartridges, making it a capable choice for deer, elk, pronghorn, and black bear.
- The monolithic copper body drives straight through on heavy quartering shots where conventional bullets can shed their jackets and lose penetration, giving you dependable performance when the angle is not ideal.
- Lot-to-lot consistency in the Heat Shield tip means your handloaded ammunition shoots to the same point of impact every season, so you can trust your data without re-confirming zero after each new box.
- The optimized grooves keep fouling manageable in the field, a practical advantage during a multi-day hunt when a full cleaning session is not always possible.
- Whether you are launching this bullet from a compact 7mm-08 or a hard-driving 7mm Remington Magnum, the CX (282704) expands reliably across a wide velocity window from close-range shots to distances well beyond 300 yards.
- For the reloader building a precision 7mm hunting load, the Hornady CX (282704) rewards clean brass prep and careful powder work with the kind of downrange accuracy and terminal consistency that keeps you confident when it matters most.
The Hornady CX (282704) 7mm .284 diameter 139 grain copper solid is a proven platform for the serious reloader and big game hunter who demands lead-free performance, high weight retention, and long-range accuracy from a single purpose-built projectile.
