Re: 270 sight in
PA/MDbowhunter is correct, but that is confusing to some people. If you put your rifle on a solid rest, and have someone turn the elevation adjustment down,you will see the crosshair move up. And the same holds for windage adjustments. But if you follow the movement mark (usually an arrow) under the scope cap, up will cause the scope center to rise. All scopes have prisms that turn the image upside down at the large objective end and reverse it before it reaches the eyepiece.
I suggest the OP try another scope.
