My 78 yoa neighbor gave me her Hunter 440 pellet rifle she uses for Squirrels and asked me to sight in the scope (a BSA). I have never used a scope, just iron sights. She told me her grand children were playing with it and now it won't hit a thing. Someone got some sort of solvent on the outside and it ate away the rubber grip coating. Everything was locked up. I cleaned the scope and then tried sighting it in. Good groupings but all shots were extreme right, like a foot over. I tried adjusting the scope but it is now down tight and still 5 to 6 inches to the right. Elevation is fine. Is there something else I need to look at as the cause? Scope is tight to the rail and no wobble.
Any suggestions would be appreciated. Thanks.
