It could just be that you were trying to get a picture, but your crosshairs are canted. You need to make sure that they are level. First make sure that the scope is mounted level in the rings, then use the vertical sides of the target to make sure that the rifle is level on the rest. (Yes, I use a level on the target when I mount it.) You can buy a kit to level the scope and a scope level that mounts on the rail to keep the rifle level. It is important for getting the best results.
