I've said it before and I'll say it again with no disrespect to the .30-06, but if you want 2900fps out of a 180gr .308 bullet, buy the .300WM. It was designed to achieve that velocity safely and easily.
As far as recoil goes, I've found a great way to acclimate yourself to the .300WM. But a .416 Rigby and put a hundred rounds or so through it. After doing this the .300WM will feel like a .243! :cool:
