A real critical dimension is the distance between the line of sight and the base of your stock. The exact height of the scope above the line of sight is, from a gun fit perspective, perhaps less critical.

If you have a 2.5 inch scope/barrel offset JSB exact at about 11.2 ft lb require one 1/4 MOA click per yard from 38 to 54 yards - which is quite nice.

Go any higher and a scope with 1/4 MOA clicks will result in aliasing of the rangefinding; ie your ranging will likely be more resolute than your ability to compensate the POI. Range to the yard at 50 yards but with a 4 or 5 inch scope height each 1/4 MOA click will be worth 1.5 yards. To go with a higher scope than 2.5 inches I would personally want a scope with 1/8 MOA clicks.

Ultimately you have to set the gun up so that you are comfortable and stable across a wide range of positions. This could entail a scope height anywhere from 2 to 5 inches above the barrel. Extremely high scopes can cause some difficulty at very close range and can increase the risk of hitting objects well below the line of sight; there were some very steep downhill targets at the Italian world championships which were very difficult to take without hitting the ground just 4 or 5 yards from the firing line. A very high sight line just made this more difficult.

There is no right or wrong just swings and roundabouts, there are very good shooters who use very different set ups!
