Jeff, I aint questioning your description of your scope mounting technique, it sounds fine.
I am a little curious about your results, however.
In looking at your rifle, and the picture of your standing shooting position, with the erectness of your head, I am having a little trouble imagining the contortions you must go through to shoot from prone without getting whacked.
I don't believe, prone, I could stretch my neck far enough back.
But, if it works for you, you have my consent to mount your scope anyway you want. Just not thinkin it would work well for most.

Democracy is not freedom. Democracy is two wolves and a lamb voting on what to eat for lunch. Freedom comes from the recognition of certain rights which may not be taken, not even by a 99% vote.
