I love my 721 in 30-06. It was my grandfathers and now its mine. I have shot all sorts from it with adequate results. Winchester's Grey box in 150 gr and 165 gr. was my go to for a while.
Currently I am loading my own with very good results, if that is up your alley I can give you my current load, though I am tinkerig still. Gor years I just used the Winchester grey box, though my grandfather liked Hornady's silvertips in 180 gr and 165 gr. (I have a bunch of boxes left though they are from the 70s. I'm not sure if those are still around).
The 721 is a work horse and doesn't need to be babied, though watch the extractor from what I hear if it breaks you have to find a work around with a Sako extractor that has been machined to fit. Otherwise enjoy it. I really do love that rifle.
