I had the same sort of issue with a "new-old-stock" Redfield 6X that I purchased from a dealer who was going out of business years ago. I didn't use the scope for several years then mounted it on a 10/22. The crosshairs went slightly blurry after each shot and the point of impact always shifted a bit. When I inquired about getting it repaired, the consensus was that the erector tube which contains the crosshairs inside the outer scope body wasn't being held in place by the adjusting mechanism. Getting it repaired would likely cost more than the scope is worth. Unless you can convince Bushnell to repair/replace the scope on warranty, I'd suggest donating it to somone who teachs a firearms safety class to use as a display item on a non-firing rifle. Your hunting or shooting success or failure depends on the reliability of your scope so consider buying one that has a good reputation for quality and leave the bargain basement ones to someone who isn't as smart as you.
