actually, your reticle may not be canted at all. don't know about your scope, but most have a circular tube that holds the crosshair. when making adjustments, you are simply pushing on the outside of this tube either on the side or the top. the farther you are away from the center of adjustment, you will actually move the horizontal when changing the verticle. again, the farther away from center you are, the more it will affect the other adjustment.
