I have 2 Savage rifles, but neither has the original barrel on it, since those, while giving "acceptable" hunting accuracy, were so-so, IMHO.
One now wears a Pac-Nor, the other wears a take-off 40X Remington Barrel. [Sure smartened that Savage up!!,

lol]
Lest someone babble about older Savages, these are both Accutrigger models, so not that old. BTW, only one still has the accutrigger, and it is scheduled for replacement.
I also have a couple of Rugers, but only one has the factory barrel, the other a Shilen.My gunsafes hold plenty of Remingtons, though, and while there are a few aftermarket barrels there, most have the factory tubes on them.
A 222 Remington, a 244 Remington, a 7x57, a 300 Savage, a 30-06, an 8x57, a 300WM, etc, etc.
All shoot very well indeed.
Several are absolutely stock except for trigger adjustment. Some have been bedded and/or Free-floated.
An acquaintance just bought a brand-new 700CDL in 7mm Rem Mag. Does it ever shoot!!
Another has recently acquired 700 SPS [I don't care for the finish] in 30-06...same thing, shoots lights out!
I have heard of substandard rifles coming out of Big Green, but I have recently also heard that BG is listening to the concerns of customers, and is making adjustments to rectify issues.
I think they should drop the 770 series, though! No matter what they do at this point, buyers are avoiding it like a plague!
FWIW, the 3 770's I have shot at the range all shot decently.
Personally, I will continue to buy and use Remington rifles, simply because in my experience, they work, and work well.
Eagleye.
