I have a Borka but mainly use it on the base (rails etc) with thread locker. 24" pounds does it.
For the rings (mainly use Burris with inserts) I tighten them until there is a space between the upper and lower ring that is about the thickness of a credit card, or so. I make sure both sides are equal and the front and back rings are equal too. Kinda hard to mess up with the Burris inserts. I have not used thread locker on the ring screws. Maybe I should?
I also make every effort to have the rings as close to center of the turret/objective, turret/ocular as reasonably possible.
I am definitely open to constructive criticism of my approach.
