HORNADY

Hornady® Superformance® Ammo utilizes special propellants that increase velocity up to 200 FPS without extra chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy. That extra velocity—in conjunction with the premium mono-metal copper alloy GMX bullet—delivers enhanced weight retention and expansion for maximum lethality.

NOTE: While the 5.56x45mm NATO round will fit in a .223 Remington chamber, 5.56 NATO is a military round that runs at higher pressures, and is not recommended for use in .223 Remington chambers.

Increase your rifle's performance up to 200 fps without extra chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy.
