with respect, the military uses the 556/223 round because a soldier acn carry plenty ammo,this round is accurate,works well in a M-16 , and another reason it wounds the enemy soldiers very good, so then the enemy needs two soldiers to get the wounded soldier back to their camp. that`s the reasons for the 556/223 you wound one soldier and it takes out three enemy soldiers fighting against us. the round was developed for the military not just for hunting.
