Possible the scope is defective. When you were adjusting too the right did you point of impact change any to the right? If so how much before it quit moving? You may have run out of adjustment. In that case you'll need to get a type of scope base that allows rough windage adjustments with the base and then use scope adjustment for fine tuning. If you go this route then center the scope reticle before mounting the scope too give you maximum adjustment in both directions.

Are you using a windage-adjustable base? Are you using a high-magnification scope?

A simple solution, if you can't adjust the base, would be to use rings that have windage inserts (think I got the name correct).

You shouldn't have to use windage adjustable mounts unless something else is amiss with the set-up. Maybe the base holes are not tapped concentric with the bore. Is it a new rifle? If not has he ever had a different scope on it before? The scope could be defective even if it is an expensive one. Did the point of impact move at all to the right when he adjusted it?

I saw some interesting tests for scops the other day. You might start by putting the scoped rifle in a shooting vice so it can't move then crank the windage all the way the other way while watching the cross hairs aimed at a grid at a distance of >100 yards. make sure the rifle and the grid are level ( you can use a plumb line for the grid target and a sope level of the rifle.) If you can't move the cross hairs accross the grid to the leftward direction when it is maxed to the right then the scope is defective, repair or replace accordingly. With this same set up you can do a box test on the scope to test the tracking and save the $ you would spend shooting a box test which tests the combo of rifle/scope/ammo.

what type of scope is this? the manufacturer may have a warantee that is transferable.
