Given the bullets in each provides the capability higher BC's you can find a high BC 7mm bullet.
And the slightly wider neck in a 7mm which lets you have potentially higher speeds with the same weight bullets.
Isn't the 7-08 better for the following reasons -
1) Wide off the shelf availabilty of ammo
2) Very possibly a higher resale due to popularity
3) Wider range of bullets
4) More brass available
I think it is..
lot's of 308 brass for both
