I agree. It is very light. To drop any large game you want at least 2,000 foot pounds of energy. The largest .223 round is 77 grains, with a velocity of 2,750 FPS (Remington Sierra MatchKing), giving it only 1,293 foot pounds of energy at the muzzle.
A 175 grain .308 (Winchester Match HP) has a velocity of 2,600 FPS, which gives it 2,627 foot pounds of energy at the muzzle.
A 180 grain .30-06 (Winchester Match HP) has a velocity of 2,700 FPS, or 2,910 foot pounds of energy at the muzzle. Even at 200 yards the round will still be traveling at 2,250 FPS and have 2,020 foot pounds of energy.
A 190 grain 300 Win Mag. (Winchester Match HP) has a velocity of 2,950 FPS, which gives it 3,672 foot pounds of energy at the muzzle.
