If you want some factory stuff to start Midway has the nosler custom 225 partition ammo in stock. Pretty good.
Good choice on the rifle too. My 700 classic is a very nice rifle.
That's what I've been using in my 673. At least once a year it goes on sale which makes it a little more palettable. With it the rifle shoots into .50 - .75 pretty consistently and I'm only trying to sight it in to go hunting. The darn thing has ended up being one of the most accurate rifles I own.
