I think it's a good idea to use some sort of thread lock when mounting rings/rails & scopes no matter what. Over time they could loosen up and more than likly it will happen just when your going for that once-in-a-lifetime shot and you wonder why you missed.... jmo.
Where exactly are using, how putting it on? I notice on at least one of my rifles, the scope mount holes go clear into the action.....seems locktight would get in the action if I used it on those screws.
I ran into trouble using the blue had to get my smith to extract bolt he says never use nothing but a little grease. and don't over tighten thats the words of the great Danny Johns
