While they do have a pretty good rep, I've had and seen enough problems with Remington 600/700 rifles not to call them "stone nuts reliable."
I've had bolt releases jam open, seen trigger get enough goo in them, usually from the opening for the safety, and even a busted extractor or two. To say nothing of having them lock up if the ammo was too hot.
I've had one Ruger, with a super hot load and one 98 Mauser with same extract and eject the fired case with the primer completely gone. Never seen a Remington that could do that. E
