I would use blue loctite on them and torque to spec.
I mounted a set of Leupold dual dovetail rings on my 700 Varmint Synthetic a dozen years ago per their directions. Cleaned the bases, cleaned the screw holes with alcohol. Applied oil to the screws and installed them according to their site. Same with the scope rings-cleaned and applied a very light coat of grease to the male dovetail and twisted them to alignment. Approximately 20 inch pounds of torque to the base screws. Never did have an issue with them until recently when I noticed my groups were really bad with known reloads which in the past proved to be good.
Thought it was my form, kept trying to adjust my position behind the rifle and then noticed one of my ring screws was loose. Fool that I am, I decided to try and fix the thing at the range. Removed the scope so that I could get at the base screws to check them-ended up snapping a base screw off at the head! The rifle is at the smith's shop right now getting it removed and I am getting new screws for the base and rings just to make sure.
In a conversation with the smith, he states that the screws should be installed dry-cleaning with an evaporating solvent and torqued to spec? Never heard of such a thing.
What is the general opinion here-dry, oiled, loctite?

I was thinking maybe at least oil or Loctite-bare threads have a tendency to give false torque readings.
How is everything up in Yooper country?
Sure do miss the place-spent a lot of time at my grandparents place near Marquette years and years ago.
They said it was God's country-he was the only one who knew his way around up there!
I use blue loctite. I have seen quite a few screws some lose without loctite.

Blue Loctite. It serves as lubricant and sealer.
Thank you all for your advice and experience. Headed off for some blue Loctite!
I run mine totally dry. The scope rings compress enough to provide tension which keeps the screws tight. They're so small that any thread locker on them may cause the heads to strip or the fastener to even break when removed at a later date. It's not necessary on the actual ring screws and can be a major problem in some instances. With that in mind, best to avoid. Just use the thread locker on the base mounting screws and then put the tube away.
