...I have a chance to buy a mint condition first production run 110 ... I expect an early savage rifle to be more accurate then other old rifles of that same period just because the newer ones will shoot others under the shooting bench...
Older may not be functionally better, in this case. A high school hunting partner was given a used 1964 vintage 30/06 Sav 110 for deer hunting. Barrel would heat, and throw rounds towards the 1:30 direction. With one magazine of rounds, he would have a string that started near the bull's eye and stretch 24" long. Of course, not every barrel was "straightened" at the factory, and most will not have that problem. But Savage did straighten malformed barrels...
More importantly, the extractor was very weak in the early version. Stamped, folded spring steel extractor claw would occasionally skip over the case rim. I think the extractor was improved about 1968.
My point is, if you want a nice rifle to hunt with, you may want to look for one of the well-made delux versions that came 1968 or after. Also, I don't think the 110 has ever had better features (esp. trigger) or workmanship than the current crop. Shooting from the bench may not matter. As long as your target is 24" or wider.
