It is in the area of windage and elevation adjustments that scopes fall furthest from perfection. Both are controlled by dials, or knobs, located on the adjustment turret, which is midway down the scope tube. The elevation dial is at 12 o’clock, the windage at 3. These dials, via a system of small, fragile, and treacherous parts, shift the position of the crosshairs, which in turn moves the bullet’s point of impact. Most all scopes claim to change the point of impact by 1⁄4 inch per click at 100 yards. In reality, they (including scopes in all price ranges) do what they please. Four clicks of right windage may move your shot a half inch, or an inch and a half, or not at all—and you just have to live with it. What’s more, all these small, fragile parts can be shaken loose by recoil, or by a fall, or by baggage handlers. In the past four years I’ve seen four scopes come unglued from these causes.
