I don't know about the bbl quality of Remington factory bbl's now vs say 15 years ago. The only 700 I have recently fired was a BDL in .300 Win that would shoot softball sized groups at 100yds with just about anything my friend fed it. This rifle was maybe 2-3 years old. For comparison this same friend has a Sako 597 that will stay right around 1-1.5 inches in his hands, and another Sako 75 in .338 Win that is a consistent 1.5 inch rifle for him.
Of course this is one anecdotal 700 BDL that would not shoot up to par. Take it for what its worth (not much). I can tell you, and most will not argue, that the fit and finish of Remington firearms in general have gone way, way, way down hill in the last 5-8 years. A 15 year old 700 BDL or even ADL will have nicely polished metal with nice even bluing, and there won't usually be coarse machining marks left around the ejection port.
Current production 700's of any flavor I have seen recently (like tonight in two different stores) had poor metal finishing, lousy bluing, and no effort made at all to polish out machining marks. Now those rifles could shoot like a house on fire and still be butt ugly, like a Savage, but then again for the asking price..... why not just buy the butt ugly Savage? At least there is an excellent chance the Savage will shoot well.
I can also tell you that the Winchester Model 70, a new South Carolina FN made rifle, shoots pretty well (another 1.5 inch rifle). Much better with the same ammo than the now departed 700 BDL.
