Well heck John, I'll add my 2 cents for what it's worth. I'm going to take a stab and quess more elk are hunted with a 30-06 every yr than most any other caliber, And a lot are brought down with one too. But I quess My vote will have to lean toward the 300 WBY mag with a 180 gr pill. I sure enjoy shooting my 6.5 or 308 better on the range but I like the energy the 300 wby gives me when I need it.
