A 223 is what it is, but I cannot equate a 40gr lead bullet at 1200 fps, with a 70gr TSX at 2900 fps.
If you can, well, I believe you.
I've killed a pretty big pile of deer with a .22LR. Somehow I doubt Elk with a .223 would be any more difficult. Course if you're one who needs to shoot 700 yds. I can see it being a different story.
