When this sort of thing happens in a factory bolt rifle, the culprit is usually the factory base attached to the receiver (the holes drilled and tapped out of alignment for left or right misalignment), or the receiver was formed/milled out of alignment with the bore.
You could try and mount a 20 or 30 moa base backwards to give the scope more down adjustment to start with.
If the axis of the receiver where the barrel shank goes into has an upward tilt, that could explain things.
Check with the receiver level, a level on the scope base and a level near the muzzle and see if there is any cant.
