I would tend to disagree with that statement. While the .308 isn't the best round for long range, many guys have extensive experience with it (and the training and practice under their belts to make it work) because of LE or Military experience. The .308 is also extremely forgiving for beginners in the loading dept and in the recoil dept, which makes it even better than a .300 Win Mag under 600 because it so easy to shoot. I have take several big game animals cleanly at ranges to 605 yds with a .308 and wouldn't hesitate to use it again.
