You might want to test the scope's turrets. If you can manage it try to clamp the scope (or rifle and scope) in a workmate, or similar, and focus the scope on a light coloured surface, perhaps with reference marks. Dial while you look through the scope, as you dial to move POI up the ret should move down on the target surface. Try doing a box test, that is dialing 20 clicks up, 20 left, 20 down and 20 right - you should come back to the origin point.
I'd be surprised if the turrets are knackered as they have an excellent reputation and none of mine have ever broken, nor have I ever heard of turret failure.
Don't be too quick to change kit, all of the scopes you mention can do the job. Hancox joint top scored at that GP and I presume he was using his Deben, the cheeky sod called mine his spare scope at GP2! Are you sure the rifle is spot on, is all the basic stuff covered - ie are the mounts loose or is the scope at the limit of its range of adjustment?
I know it can be difficult to shake doubt once some bit of kit is questioned, but if you just blame the scope without some sort of investigation changing the scope might not fix the problem.
