I like the 7mm-08 a lot especially at the ranges you are talking. With the different websites out there, factory ammo is always available.

I also agree with most that a poorly constructed bullet or pushing a bullet faster than intended leads to destruction, hitting a heavier bone doesn't help either at times. For the ranges you are talking, a bullet going 2200-2800 fps is more than adequate and your choice in the 308 is a good one. Personally I have had a couple of 308's and liked the 165 and 180's as where I hunt, 90% of the shots are under 150 yards
