Hunting is one of those areas where from time to time the question isn't "can I?" - but rather "should I?"
Yes, at the end of the day - we're killing wildlife - but I think we have a bit of a moral responsibility to do so humanely. In that light - I wouldn't choose a .223 for anything other than varmint.
Bullet energy at 100yds from a .223 (50gr at 3000 ft/sec) is roughly 909ft pounds.
Go out to 200, and you're only at about 674ft pounds. 300 it drops to under 500 ft pounds. The energy just isn't there for a reliably clean kill.
Now a lot of people ask "how can you really claim a 243 is so much better, when it's not much bigger" - again, look at the energy. (100gr @ 3100 ft/sec)
@ 100yds : 1788 ft lbs.
@ 200yds : 1486 ft lbs.
@ 300yds : 1228 ft lbs.
@ 400yds : 1009 ft lbs.
The difference in energy is pretty clear. You've got more energy from a .243 @ 400 yards, than you do from the .223 @ 100 yards. The .223 - while it *can* work with excellent shot placement, again just doesn't have the energy for a consistent reliable kill.
