Terry,
I know this doesn't answer your question directly, but I do have the Nikon Buckmaster 4.5-14 X 40mm mounted on a Stevens .308 and it has proven to be an excellent scope.
My shootin buddy has the Buckmaster with the BDC reticle mounted on a Swede and he loves the scope.
I prefer Leupolds, but if the Omega is built like the Buckmaster, I would think you would be very happy with the scope.
Dave.
