Can't sight in - Hi-Lux Optics Long Eye Relief 2-7x32mm LPVO Rifle Scope, 1in Tube

I have two of these scopes mounted on Mosen Nagant M-38's with Brass Stacker Mounts. My gunsmith mounted them. They were bore sighted using adjustments on the mounts and then the optics. They were bore sighted at maximum power. It was noted that changing the power after bore sighted the crosshairs moved radically. At the range at maximum power
at 50 meters totally ran out of adjustment with both windage and elevation. Calls to Leatherwood did not help correct anything. I don't understand how others can give this scope 5 stars.
Pros: None
Cons: Everything
