The old Remington 721's are pretty solid rifles if you can find one these days.
Hard to go wrong with a Pre 64 Model 70 '06. Next, have to determine the vintage you're interested in- Pre War, Transition, 50's/60's, Featherweight, Supergrade, etc.....
I own several and I've never regretted carrying them into the field or to the range. Always accurate, always reliable, handle well, appreciated by everyone in camp.
