I think during that era, the general consensus was that a bolt action hunting rifle did not need more than a 3-9 power scope. I personally disagree and think that something that goes up to at least 14 power is the way to go. You don't have to use all of the magnification, but it's nice to have if you want it. 4-16 is the smallest I own, with several going up to 20 to 24 power. YMMV
