no doubt the .308 is better but with decent ammo (ie the 77gr blackhills for 1) the 5.56 will do the job.
isnt it odd that the 5.45X39 is similar to the 5.56 but no one ever implies that the 5.45 is lacking, the afghans called it "poison bullet" lol, i suppose the bullet is designed to tumble, but still its always made me wonder WTF is up with it.
really like my AK74 by the way, and the 5.45X39.
but also like my colt lightweight sporter AR15 a lot too, wouldnt feel undergunned with either one.
