308 vs 30-06 family accuracy

[Mutt]

I looked at one of these at my local gun shop. It's a nice little rifle and would make a great mountain rifle. It's small and would pack well. And, it's chambered in .308

As far as velocity goes, your looking at loosing about 150 fps for about ever 4 inches of pipe (with a .308) ..... I think. So, if you are shooting a 20 inch, a 24 inch would have 150 more fps ..... to a point anyway, then it drops off.
