Hard to say or give the value without actually seeing it. If it is in deed at 98% then it should not have many rounds through it and the actions alone are going to approx. $400.00. Should make a fine deer/bear rifle for up to 500yds. The Remingtons made back in the late 60's should be just fine. The quality, IMO, was a little better then than now. JohnnyK.
You have a very nice rifle and I expect it will be extremely accurate, same rifle I used while growing up in Idaho. Many mulie and whitetail bucks fell to that rifle. I bought another one when Remington brought it out in the 'Classic' and it also was a great rifle, had it fitted with a McMillan stock. I used it up here and killed several moose and caribou with it. I have two boys and when they turned twelve, they had their choice of a new rifle or one from my collection. The youngest chose the 7 mag so I no longer have it. He is now 27 and it's his 'go to' gun. He shot at the range with me on Friday and it still shoots a one hole group at 100 yards. He will be taking it to Idaho in November when he and I go down to hunt whitetail.
You bought a very fine rifle. I purchased my first new rifle in February 1968 when I got out of the military. It was a Remington 7mm Mag 700 BDL. I shot everything from fox to elk and moose with that gun. It would shoot under an inch @ 100 yards. The gun was stolen in 1979. I still own a Rem 7mm Mag, but I sure miss my original one.
