    55 Grain 223 FMJ Ammo
    Average muzzle velocity – 2867 fps
    Average muzzle energy – 1004 ft/lbs
    Bullet drop at 500 yards – 75.02 inches

    147 Grain 308 FMJ Ammo
    Average muzzle velocity – 2672 fps
    Average muzzle energy – 2330 ft/lbs
    Bullet drop at 500 yards – 61.42 inches

    Slower bullet, just barely, but 2x the energy.
