Not reliable - Bushnell Elite 6-24x40mm Mil-Dot Reticle Rifle Scope

I have had this scope for several years on my Remington 700 chambered in 308 Win. It always had the problem of not actually make any adjustments on the windage and elevation until the second shot. About a month ago it dropped its zero completely and would not re-zero. I sent it back for repairs. When it came back The elevation would no longer allow for a zero at 200 yards (I did not change any of the mounts on the gun). Bushnell told me that I needed to "shim" the front mount on the gun to fix the problem (basically they said my gun smith did not know how to mount a scope properly). This is not a reliable scope.
