Loctite them scope screws!

Use proper torque wrench and manufacturer # inch pound recommendations.
Usually 25-30 inch pounds for base screws and 15-20 inch pounds for ring screws.
Never had a scope loosen up yet even on the 45-70s firing Buffalo Bore ammo.
Use a special tape on inside of rings so no lapping either.
Once our scopes are zeroed they stay zeroed.

There should be no oil on the screws or in the threaded holes in the receiver. The insides on the rings, bottom of bases and top of receiver should also be oil free. Locktite on the base screws only and torqued to manufactures recommendation. Use quality bases & rings and the scope will never move under recoil and the base screws will never become loose.
 
Actually I think torquing only works when thread pitches are right .. and well, I've seen far to many come loose over time, even without rough handling.

I always use loctite now and double check, on bases and rings, just a little bit of insurance that works.
 
I never use loctite on ring screws, and the screws never come loose. I had no issues with scopes moving in the rings even with my 300RUM and 338x8mmremag rifles, and they didn't have brakes.
 
well....

pre hunting season check list includes...
- check on tightness of all scope mounting one piece plate screws and then scope ring screws. (suggest one piece mounts)
- with rifle in quality gun rest/table, fire half (less if accuracy obvious) box of main ammo used at game (in field), over a time period such as your barrel does not heat, and fired at range to assure zero and repeatability. Zero as nec.
- re-check on tightness of all scope mounting and ring screws
and:
if any scope and or mounting screws took even a third turn see point 2

Never had an issue following this simple policy...and have NEVER applied any Loctite or such...

Has anyone ever seen Loctite in the stick form instead of liquid? I have looked all over and haven’t been able to find it. Maybe not available in Canada?
 
If using loctite anywhere near an expensive scope, always give the scope body and inside of the rings a coat of clear shoe polish. There's nothing worse than finding out loctite leaked from the screws onto the scope rings. With a coat of wax on the scope, loctite is much easier to remove.
