Had a scope mounted on a rifle by a "so called" reputable gunsmith years ago, when I decided to replace the scope because I had to constantly re sight the rifle, turns out the front base was loose. Since then I have always mounted scopes myself and used "blue" loc title only. Torqued to manufacturer specs and have never ever had any more problems. A friend who is a millwright and machinist said the loctite won't affect the torque by the threads not being dry. Hope this helps.
