Welcome Dan.
Until you get used to shooting the 06 I would recommend shooting some 150gr. reduced recoil from remington (helps to avoid flinching, save the brass). Once you have mastered the recoil you can use anything from 110gr on up, that's one of the nice things of the 06 the variety of ammo for it. Look into buying the bulk ammo for now you can buy 100 rounds for a $100 or less, if you can find some place that sells surplus ammo I'm sure you can get it for much less.
there are draw backs to everything and the draw back to factory ammo is the fact that pinpoint accuracy is not going to be there, unless you spend a lot more for match grade ammo.
IMO (probably worth less than .02) until you reload and until you are used to shooting your new rifle buy the cheapest you can find and save the brass except for military surplus, shoot often and shoot safe.
