What kind of rifle?

I know for smallbore, but not for a big bore rifle, sorry. A suggestion though, torque it up to something that feels right and test it on the range.

Rings: Do not use torque wrench. Use the 'L' handled torx wrench that came with the rings and hold the short end. Tighten rings as much as possible using one hand holding the short end of the 'L'. This is the best way. I have heard 15 - 20 in lbs for the ring caps, but I can't confirm. You risk crushing the scope tube.
Rings to base: This depends on what kind of rings you are using. If you have rings that attach to a Weaver or picatinny base with a nut as opposed to screws then 55 in lbs is about right. Not sure about rings that use a slotted screw to secure to the base.
Base to action: This also varies on the type of base. Badger quotes 15 in lbs. Ken Farrell says 20-25 in lbs depending on which screw (front or rear).
Action to stock: Many say 65 in lbs. I think this is too excessive. I shoot for 50 - 55 in lbs and make sure all action to stock screws have the same torque.
BTW: Don't use loctite if you're going to torque the optic mounting screws. You only use loctite when you don't have access to a torque wrench. And never use loctite on the ring cap screws.

I was reading de Haas's book on "Bolt Action Rifles", and concerning the Remington Model 700, he mentioned that over-torqueing the action to stock screws will frequently split the stock, and further says that glass bedding the action will prevent this. I have never read of this problem in over-tightening the action to stock screws on Remington M-700's. Anybody know anything about this?
The Remington manual gives no information on how tight to torque the M-700 screws but I have read elsewhere that 45 inch-pounds is recommened. Not sure where this figure comes from. Without a torgue wrench, how do you know how much to tighten these screws? I always hand tighten them as tight as I can and no stocks have split yet? Any info from the experts on this?

Maybe I'm wrong, but I've always been told that anything above 45 in lbs. the wood starts to crush and this can lead to cracking. Glass bedding and pillar bedding can provide a hard surface to torque against allowing a higher torque setting.
Please feel free to correct me if'n I'm wrong.

Without a torque wrench. how do you tell if you are approaching 45 inch-pounds? Would that be just "snug" or "really hand-tight?"
