That sucks. It could be a number of things. What mounts do you have? They could have shifted unless they're nice and beafy. Heck, depending how things fit together, especially if the objective hangs way out in front of the front ring you may have tweaked the tube, it wouldn't be the first time I've seen that from a scabbard.
But there's no doubt those tall turrets can help things put a bunch of leverage on the scope. If it was mine and I wanted to keep using it, I'd send it in for M2 turrets (I think they can put those on that scope now). Much more scabbard friendly.
i have a 6-20x40 luppy that i just got back from Cecil Tucker's. my POI didn't seem to be repeating so i had him put his tube/coil spring/ locking screw on it. when i say just got it back i mean a few hours ago. haven't had a chance to try it. i'll let ya know how it does/i like it.
Don't know about these new VX-3 but I can't remember having that problem with my VariX-III. I transported my rifle like you do in my mountain bike trailer with no change in zero. Send it back to Leupold and have them check the scope.
To achieve the maximum possible accuracy, all variables must be remove or at least minimize.
I've got a slew of Leupolds, a Nightforce and a Kahles. Of all of my scopes, many of which have traveled thousands of miles, guess which was the only one to give me problems. The Kahles - they repaired it for free but I sure was surprised.
Knock on wood - my Lup's have all been great. I've got a Nikon Monarh on order but am very concerned by the thousands of "Refurbished" Nikons that are always available through some of the major internet retailers.
I'd love to have all Nightforce, Swaro, S&B and similar optics but that just isn't in the cards for me. It's not that I can't afford them, it's that I can't afford the divorce!
