Scope for Rem. 700
I don't shoot factory ammo so I can't help you there.
As far as a scope goes you will find a multitude of varying opinions.
IMHO the best bang for your buck is NIKON. I'm not fool enough to say "best scope" however I do say "best scope for dollar spent".
Again, this is one of those varying opinions.
Nikon Monarch 3X9X42 is my suggestion for your Rem. 30/06.
GOOD LUCK and GOOD SHOOTING!!!
