Out of the 10 or 15 Remington's I have done load development on, or bedding jobs, or any kind of minor work, all have shot very well, as in well under MOA, and most shot under .75 MOA. You will find that MOST (not all) of the people talking bad about Remington's, actually have very little experience with them, or are not capable of fixing relatively minor issues, such as bedding, action screw torquing, or proper optic mounting, or are novice reloaders. Which is fine, that is why there are gunsmiths, but if someone buys a new rifle and it needs a little work, it can be discouraging to them if they don't have the knowledge or experience or tools to fix it themselves. Yes there are some manufacturer defects from time to time, I know it is common for the belted magnums to have rough chambers, and brass will stick. I had to lightly polish the chamber of a stainless 700 Long Range in 7mm rem mag, but after that it has been great, and is shooting under half MOA with Berger 168 VLD'S. Another identical rifle shoots 180 VLD's at 3015 fps, and is holding a loose half MOA.
And if you have a smith rebarrel your rifle and go through it, a Remington is just as good, if not better (because of the aftermarket support), than anything else out there.
