The 06 has flatter, faster trajectories than 308 when compareing apples to apples. On smaller bullets the advantage is small but there just the same. With heavier bullets the 06 is very much superior.As a reloader the 06 has more upside potential than the 308. The one advantage that the 308 has is short action, like the 06's velocity advantage w/ smaller bullets this to is a very small advantage. As to the comment that the 308 fits him better...give me a break....thats the rifle ,NOT the 308.
