I am switching my base from a flat base to a 20 moa on my 700 sps. Will bedding the base matter after the scope has already been mounted to it. Will the scope flex back to normal?
 
You really need to bed the base by itself, then mount the rings and the scope that way you can ensure the rings are mounted perfectly true and square to the base, and you can check ring alignment with a mandrel prior to mounting the scope.
 
The amount of unevenness that a base and action might exhibit should not be enough to cause any permanent damage to a quality scope.
 
as well as the fact that your rings might not line up perfect with the new base. the grooves in the rail might not be 100% in the same spot. If you are worried about having to re level and all that what you can do is remove one of the rings and leave one still attached and tight. Then after the bedding sets and you're ready to put it together you just have to put the detached ring in a close to where it goes spot then attach the scope with one ring on it then attach the ring and double check level and bore sight. Saves a little bit of time. Just did this swapping to a 20 MOA but didn't want to have to re level.
