Scope Cant

[SagaciousKJB]

If the vertical crosshair is not bisecting the image in the mirror of both the objective and the bore, you need to rotate the scope in the rings until it does....

Well that's the thing, it is and it isn't depending on where my cheek is on the stock...  Kinda hard to explain.

If a scope mounts off center as bad as A shows you have a serious problem that probably can't be fixed. I level the breech and then continue with a plumbob or level. I have seen dovetails cut not straight  with barrel  but it is rare. No real fix except drill it for a rail of some kind.

Actually, Scalf, you could mount the scope on the side of a receiver and have it work fine.... However, you would have to hold the rifle on it's side to shoot it, so that the "vertical crosshair" (the one pointing towards the bore in the mirror) is vertical.... Mounting a scope as in "B" will work even if it is a long ways off the centerline of the rifle, PROVIDING you then hold the rifle canted as in "C" so that the vertical crosshair is vertical when shooting.....

Sagacious, if the crosshairs move around when you move your head, you have a parallax error, you are not focused to the distance from the scope to mirror and back again.... This may be because you have the ocular lense focused wrong, it must be focused on the reticle, so that when you focus the objective, the image of the target (in this case the scope and bore) is in the same place as the reticle.... If they are not, when you move your head, the crosshairs will appear to move on the image (or vice versa)....

Or you could just aim an inch and a half to the left.

Bob, I knew you would have an answer, but this blows my mind. I suspected as much. Why can't everything be 90 degrees. Easy peasy.

That's how I feel Mark, lol
