Hemi, you may not know it but many hours have been wasted on the 708 vs 308 argument around these parts and it is a scab that some people love to rip off from time to time
There is in reality very little difference between the two calibres, 308 ammo is slightly cheaper as it is a bit more common
Dogmatix's advice is good - Howas and Vanguards are fine and you can upgrade the stocks later, Tikkas are very popular
Get good optics and spend plenty of time on the hill and range
