The .308 isn't as "popular" with gun nuts for the reason illustrated by this thread:
Any discussion of the .308 always turns into a .308 vs. .30-06 debate.
The truth is that they're very similar, each having debatable strong points over the other. For most people, and most purposes, these differences are so insignificant as to be negligible.
Enthusiasts of any ilk love to debate minutia that non-enthusiasts would never consider. It's fun.
I've got a .308 and it's amazingly accurate. I wouldn't sell it. I would be just as happy with a .30-06 if it shot as well.
