Stress Relieving?takes a couple years to stop? A natural thing?Wow my guns have shot well from the start or I found out why and fixed them,maybe Savages don' t need to stress relieve themselves(pillar bedding and floating barrels).I would suspect the scope since they found problems and changed some internals already.Parallax,unless you hold your eye in exactly the same position each time won' t result in tight groups slightly off center,but will tend to scatter your shots slightly.If possible try another scope of some kind so you can eliminate the scope as a possibility.At the same time if you use the same mounts it can eliminate them also.Synthetic or wood stock?
