mjac, I don't think that I've ever torqued scope rings or bases... or much else on my guns in 60 years; BUT, I do snug snug things down rather tightly and use blue lock-tight. My normal practice also includes once per year checking to be sure things stay tight; so far, I can't recall anything coming lose.
p.s. I do have a Wheeler torque screw-driver thingie that I did use to tighten the stock screw on my 10/22 Target heavy barrel once; after that, I just never bothered using it again 'cause I'm lazy (and it didn't seem to make any difference positive or negative).
