Default Mounting pressure for scope rings..

Badger Ordnance recommends 65 lb/in for the bolts and 15 lb/in for the torx screws for their rings. I think 15 lb/in for their bases.
Are these recommendations same across the other brands?
What do you do to make sure your mount is good and not damage the scope?

I tighten them until they're tight enough, then go around and re-check them. Works pretty well for me, but I've been working on mechanical and electronic stuff for 40-odd years now. "Tight enough" is something you just have to develop a feel for.

Also, I don't worry about cosmetic issues (partly because I buy most of my stuff used), and I've seen a lot more problems caused by too loose than by too tight.

From the Leupold web site:

What torque do I torque my Mark IV rings to?
You will want to torque the 1/2" nut on the side of your Mark IV rings to 65 inch pounds.

What is the torque spec for the Rifleman ring keeper screw?
The torque specification for the Rifleman ring keeper screw is 14 inch pounds ( 2 in. lb. ).

What torque value do I use on my windage screws?
We recommend that you use 42.0 inch pounds for windage screws.

What Torque Value Should I Use on Mark IV Rings?
The Leupold Mark IV Torque Wrench is designed to deliver the proper torque value of 65 inch pounds when installing the Mark IV rings for return-to-zero accuracy. Mark IV Ring Torque Wrench part number: 48701

What is the Proper Amount of Torque for Torx Screws?
The tightening of Torx screws on Leupold products is not best explained in terms of inch pounds or any other torque measurement. Specific torque measurements are generally only found on items that are both under the control of the same manufacturer, as in the case of the Leupold Mark 4 ring cross bolt, for which 65 inch pounds are recommended for proper installation. In cases where Leupold screws are being installed into other manufacturers products, as is the case with all firearms, we advise that screws be tightened until secure. This is always best done by feel; if the screw feels securely snug, it generally is.

What amount of torque do I use for base & ring screws?
Use 15.0"inch pounds maximum on the base screws to properly secure the base to the firearm and 20.0 " inch pounds maximum on the 8/40 ring screws.
