You may have run out of windage adjustment and are at close to the limit of your elevation.
Cranking the elevation down freed up a bit of your windage. Bit hard to draw a diagram but visualise a circle/clock and the centre of the cost hair is hard against the edge of the circle at 4 o'clock. Adjusting elevation down would move the reticle slightly into open space giving you a wee bit more windage.
It would also seem strange though if you've reached the limit in one direction or other that the adjustment didn't just stop solid. Having said that I have an older Leupold that caught me out on the elevation - it just continued to click at max elevation with no change.
Try optically centering the reticle and start again. Either by winding full the other way and counting the clicks and then come back half, or by the mirror method (google it). Throw the laser away and just use eyeball bore sighting.
Or your scope has just plain failed internally.
Strange if it was OK on the last rifle.
