Make sure the turret set screws are tight (and I mean super tight), or the turrets will slip. It's one of the few short comings of the Gen II Razor design; the knobs' OD's are much larger than the splined drum at the center of the turret (AMG solved this issue). which means you have a fairly long, skinny screw that can flex and come loose or slip on the drum. It doesn't hurt the Gen II Razors reliability or tracking, but is just one of those things to be aware of. The set screws really need to be tight.
To see if this is the issue, undo the set screws and pull the turret cap off. The black splined drum can be pulled out by using a finger nail, just get under the edge of the drum (it's a slip fit). Once the drum is out, if it has slipped, you'll see the markings on the drum from the set screw. Also, if they are fairly deep, and are hindering getting a solid zero in place because of gouging the drum, contact Vortex, and they'll send you new drums.
At any rate, hope that helps some. I have two Gen II Razors, and every "problem" I've had (two "problems") were actually user error (my fault). These scopes are rock solid; you just need to understand a little bit about the design to trouble shoot any "problems" you think you might have.
