[QUOTE="Buano, post: 452819, member: 21641"] There are only a few likely causes for your problem. From an engineering standpoint, I do not believe you have the tension you think you have — if you did the scope should never have moved. Based on that premise, the things to check: Rings are contacting each other. You said no, but some rings have an area right around the screw that sticks out slightly. Screws are bottomed out in holes. This shouldn't be possible, but it the tap wasn't run in far enough it could be an issue. Rings were lapped too large for the size of the scope so there isn't uniform pressure on all sides of the scope. Rings do not have adequate surface area to hold the scope. There is a reason many 50 BMGs have 3 or even 4 sets of rings! If you have checked these things there are several possible fixes: • Use Locktite. It works. Use 1 drop on top & bottom of each ring. • Use a balloon, yes a balloon! Stretch balloon rubber around scope & mount in the rings. A balloon is stretchable to less than .002 & this gives a rubber traction gasket that will hold almost any scope. (Gunsmith showed me that 40 years ago when mounting a scope on a 12 gauge & it worked well!) •*Add a third, or fourth, or fifth ... ring. (Be sure they are lapped after mounting on rifle as this is super critical when more than 2 rings are used.) [/QUOTE]
