Col. Boddington weighed in on this subject in a recent article and his opinion is also that the Savage is the most accurate "out of the box" rifle. He mentioned that opinion was shared by another of his editor/publisher firends but I forget who.
In one "shoot out" article I read a couple years ago the Savage came in first in the accuracy department.
That said, modern manufacturing techniques, including computer-controlled machinery, reduce manufacturing variations and allow tighter tolerances in mass produced products. The end result in the firearms market is that, on average, modern firearms are more consistent than those produced back in "the good old days". While it has always been possible to get a lemon, I think your chances are significantly less these days, at least when you are talking abouut Remington, Ruger, Savage, Marlin, the new FN Winchesters, Howa and others. Even the inexpensive Stevens rifles (under $300)
are aften very good in the accuracy department as they are basically a Savage unadorned with better cosmetics.
The fact is that most modern bolt rifles will shoot pretty well, many better than the shooter is capable of. I have Ruger, Remington and Savage and haven't noticed any significant difference between them in accuracy. In fact at my range sessions the "most accurate" seems to vary from session to session.
