kinda like when your handgun kept on shooting low left...
Sounds like you mounted it 90 degrees off.
If adjusting it for windage did nothing, then you either have the scope mounted with the windage line turned up/down (the direction for elevation), and the elevation line where windage should be (left/right) -- or you were adjusting the wrong dial.
Line the scope up on a point on the wall in your house and move the dials. See where the crosshairs move. Make sure the rifle is stationary -- in a vice, between some books, etc. if the dials cause the movement to be opposite what you expected (windage adjustment causes elevation change), then your scope is canted 90 degrees. Rotate it so the crosshairs that were vertical are now horizontal.
If the reticle is a plain set of lines without BDC or other markings, it's easy for a novice to mount it wrong without checking the adjustments to verify.
There are ways to make sure the rifle and scope are parallel, and the elevation line in the reticle is perpendicular to the plane of the rifle. No expensive tools needed. If you need help, you should start a fresh thread.
My other guess is you mounted it so crooked, the adjustment can't make that large of a correction. If the rings are mounted properly, that shouldn't happen.
