Mag,
I have no idea on those specs. You'd have to ask the folks at Leupold.
They did such a good job copying the rest of the old 3x specs, one wonders why the increase in magnification/reduced field of view on the new version.
Perhaps the new lens designs they use would not allow the exact magnification given the tube platform and lens distances. Who knows?
For me, it's still not a deal breaker. I will be buying two in the coming months. One for a 9.3x62 Mauser and the other for 45-70 Ruger No 1.
