Bonefish: I own and have owned more than a hundred pre-64 Winchester Model 70's and over the decades I have shot and still shoot probably 35 pre-64 Winchester Model 70's.
Including five or six of them in caliber 30/06.
I have as yet to encounter a pre-64 Winchester Model 70 that did not shoot at least fair.
In other words I have never personally shot one that shot poorly!
Including one Model 70 in 30/06 (manufactured in 1957) that was so dependable, so accurate, and with which I killed so much game from Bears to Elk and Mt Goats to Antelope and three kinds of Deer that I "retired" the Rifle several years ago.
These Rifles are extremely safe, extremely dependable, accurate, quality made (lasts!) and handsome - so much so that I recommend you buy the Rifle if for no other reason than for an investment and pride of ownership.
Best of luck to you if you decide to buy it.
Hold into the wind
