I guess I'm biased in this regard, because I have two Sako 75's and both wear Zeiss Conquest 3-9x40 scopes. I've hunted pretty hard with the .300 Wby Sako in particular and have fired some 800 rounds of ammo with that Zeiss on it andithasn't given me any concerns whatsoever. So, the Zeiss Conquest gets my vote.
