I bounced my rifle out of the back of my Mule Saturday evening on the way to the deer stand. I didn't know the gun was missing until I stopped to walk in. I back-tracked and found it (hardpack road in the back of the field), opened the case (basic soft sided case) and inspected for obvious damage. At that point I had two options- go back to the truck and get the backup .243, or continue to the stand. I chose the latter. I didn't shoot it Saturday. Yesterday, I put it on the bench and it hadn't lost its zero. I put about 20 rds through it bf I went home. Based on where the gun was found in relation to the track through the field, that gun took a pretty good tumble. N=1 and my story is anecdotal, but I've owned this scope for three years and it hasn't let me down. It hasn't been dialed beyond 700yds, but it's had several hundred rounds underneath (.260 boomer!!) and has performed flawlessly.
