Not sure if it could be called more versatile but it is a monster of a round in terms of speed. 4000 fps with 55gr bullets.
I think 223 is plenty for small critters and much cheaper to boot. But I have friends that are huge fans of 243 and looking at it's ballistics... for hunting, it looks like a total win to me.
...Slow, deep breath in followed by two quick, shallow exhales, then one long breath out. It should sound like "HEE HEE HOOOOOOOOooooooo...HEE HEE HOOOOOOOOooooooo". Once your comfortable with that breathing pattern, try to sync the tempo up with your heart rate. "Lub-dub...HEE HEE HOOOOOOOOooooooo... etc". ~ CBruce
