I show you at 20.7 MOA up at 800, if you held a true 18 inch hold-over, that would put you about the 2-3 MOA that you were short in your dialing.
I show 29.9 MOA and 312.7 inches at the 1000 yards mark, but it's rough math only - NV is seeing about the same.
I'm guessing a "fat-finger" data error combined, with some scope error.
I also noticed you didn't add any wind data - which plays a big factor as well.
