IMO you got one of the better 700's. There was talk about Rem changing something (the barrel broaching system?) sometime after 71 or 72. (IIRC Savage started creeping up on Rem in the late 70's early 80's.) I do know I was given one from the late 60's that was dropped off a mountain in Colorado and the bolt handle broken off. (It had been fired prior to being dropped.) When I sent it to Rem for a new bolt, the bolt they replaced the original with was slightly different. I don't remember the nuances, but perhaps someone here can tell.
Re: scope - 4 power magnifies the target 4 times. That should allow the rifleman to realize his safe maximum for hitting where he aims w/o magnifying the motion of a non-rock-steady off hand hold so often caused by higher magnifications in hunting conditions.
