Forgot to mention my only other experience was when I bought a used scope off of ebay for my 375. When I got it I could tell it was old and had been well used or maybe even abused. After mounting it up, on the third shot it went completely out of focus. Sent it in with a note explaining what happened and they sent me a brand new scope.
Count me with the Leupold loyals.

I am continually astounded at how quickly people make up their minds on little evidence or none at all.
