From the picture,everything looks OK.
If your scopes turrets are at their adjustment limits something is wrong.
Have you tried to center the reticle of your scopes on that rifle? When set to a dead center vertical/windage,you shouldn't be but a few MOA off from the centerline of the bore,and even cheap 1" tube scopes have around 20-25 moa of adjustment range either way from dead center.
Without actually seeing the rifle,it's hard to tell you what is wrong. If it was just happening to the Leupold scope,it could be a scope problem.But,your saying the Shepherd scope is also out of adjustment,so that makes me think it is a mount/base problem.
