After sighting-in at 200 yards zero I started shooting. The range where the test took place goes out to 1100 yards, but the limit of the one-turn dial is around 650 with the 140 AB load. It was basically dead-nuts out to 650, with no tweaks to the dial, so apparently the dial agreed with the Nosler/Litz BC.
I've done the exact thing with a 7-08 and VX3/CDS, and 7mags and VX6CDS dials. I've never had any trouble doing exactly what you did out to the max distance on the dial with 140-160 AB's.
