What do you torque your rails and rings at? do you use blue lock tight?

If it is tourist season, why can't we shoot them?

Depends on the manufacturer.
 
What are you using now?

I feel that is quite abit.
 
Personally, I like 16 inch/pounds for the screws into the reciever and 16 inch/pounds for the rings as well.

Yes on the 15-16"-# for ring screws- No on the blue Loctite per some ring/base mfgs.
Loctite on DNZ, for instance, voids warranty.

With Seekins rings, I use 15 in-lbs. for the ring screws and 43 for rings to base (which is the nearest to 45 that the Borka torque driver gets).
Reaction time is a factor...

I look up the max torque for that screw size.
Then I have to know what grade screw it is.
Then I have to measure how much engagement with the female threads.
Then I have to evaluate the female material; Steel is best, but it may be cast iron or Aluminum.
If engagement is more than 1.5 times the root [minor diameter of the screw] the screw is probably the weak link.
Then I have to evaluate the lubrication. Wax makes for much more tension from the same torque. Oil and grease not so much. Clean and dry is the least.
Then I calibrate the torque wrench. I use as standards, a ruler and a weight that I weighed on a balance beam.
Then I do a destructive test on sample material to verity my calculation is correct. If the female is the weak link, I mill sample material to the same thickness.

So far I have only done all this work for the scope mount screws that I drilled and tapped into a Mosin Nagant receiver.

But I have done parts of this exercise for many applications in gunsmithing.
