Re: 7mm08Rem or .308Win
Here is one scenario that the 308 would beat the 7mm08.
7mm-08 150 Ballistic tip 2800 FPS (BC .493)twist x9-10
308 155 Scenar 2950 (BC .508)Twist x12-13 for a drop differance in the 308's favor of 5" at 600 yards and an energy differanc of about 200 FPE.
Due to the larger bore of the 308, it has the ability to push heavier bullets faster with less twist.
Here is an example of where the 7mm-08 might out perform the 308.
7mm-08 162 AMAX 2800 FPS (BC .625)Twist x9
308 168 AMAX 2850 FPS (BC .495)Twist x12-13
The differance here is 4" and about 150 FPE in the 7mm-08's advantage at 600 yards.
One more example is the 178 AMAX in the 308 and the 162 in 7mm The differance is 7" in the 7mm's favor, but about 50 FPE in the 308's favor
Each has certain advantages, but it may be foolish to say that either will outperform the other all the way accross the board. With the 308's accuacy reputation and MASS selection of bullets, life of barrels and slow twist, I would choose the 308 over the 7mm-08. The 308 will shoot most bullet/powder combos well and also has a bigger bore for more killing performance as well as burn area for higher velocity with even heavier bullets. The 162 AMAX is about the only bullet that will allow the 7mm-08 to out perform the 308. Now if every rifle would like that bullet...
If you want HIGH velocity and super flat trajectories, maybe neither will suit you. About the best you can do with the 308 is a 155 Palma, AMAX or Scenar at around 2950-3000 depending on bbl length. The best you can do with the 7mm08 for flat is the 140 Ballistic tip at around 2900-2950. If you want a fast n furious varminter, the 6.5 you mentioned might be the ticket. The only down side IMO is barrel life. Other than that, its flat and accurate. This is all of course with a varmint rifle in mind.

Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
