The Hornady Superformance 5.56 NATO 55 Grain CX Ammo – 812544 is meticulously crafted for shooters seeking superior performance and accuracy. Utilizing Superformance® propellants, this ammunition achieves velocities up to 3,175 fps, which is approximately 100 to 200 fps faster than conventional ammunition, without increasing chamber pressure, recoil, or muzzle blast. The CX™ bullet is a monolithic copper alloy design that provides uniform, controlled expansion, deep penetration, and retains over 95% of its weight upon impact. Its Heat Shield® Tip resists aerodynamic heating, maintaining a high ballistic coefficient for consistent downrange performance. The optimized groove geometry of the bullet enhances aerodynamic efficiency while reducing bearing surface and fouling.

Each cartridge is assembled with premium components, including select brass casings and reliable primers, ensuring consistent ignition and optimal performance. Stringent quality control measures guarantee proper bullet seating, consistent charges, and pressures, resulting in lot-to-lot consistency you can trust. Packaged in a 20-round box, this ammunition is an excellent choice for hunters targeting medium-sized game, especially in regions requiring non-lead projectiles.
