100 or so FPS across the board in favor of the 30-06. Not a difference in the field, only a numbers hawk worries about that.
Your issue is the rifle obviously. Since we are talking hunting rifles I can honestly say that if I took two of the same model, lets say it's a Ruger American, I would not think I would find any real difference in accuracy. Dang sure no difference that will be seen in the field.
