It all depends on what you want to do, as well. Can you shoot past 800 or 1000 with a .308, sure, I do it routinely. Is a 6.5 of the flavour of your choice more efficient for doing so, for sure. You also get half the barrel life. It all comes down to what you're trying to accomplish. Are you going out by your lonesome (or with a few buddies) and trying to learn/improve your long range game? .308 might just be the ticket, you get nice long barrel life and you'll really get to learn to read the wind. Even if you plan on competing in PRS type matches, Limited division (.308s shooting 175 gr pills 2750fps and lower) is growing this year. In fact, the guys who won the team event in Limited at the last match I was at were 3rd overall. Don't get me wrong, they're 2 of the better shooters in the States but still. The winds were pretty stout and anything but stable. Both my partner and myself made 3rd round hits on a target at 1170 in some tricky winds (shooting .308). I was super keen to put together a 6.5 and still will but my current new rig that I'm breaking in is optimized for shooting 175s (the new Nosler RDFs) at 2750fps. As long as you can shoot in matches that compare apples to apples (ie have a Limited or Tactical class) competing with a .308 no longer handicaps you. Basically you can't go wrong with either...
