Ok, this may be confusing so I'll post some screenshots. There seems to be a limitation of setting for a max of 1100 yards manually. I think if you're shooting from beyond that you need to rethink your attack, but some like to shoot from extreme range. They are the ones wondering why they miss their targets...
When you pop up the range portion of the TDC, on the right hand dial there is a clear plastic triangle that has the crosshair on it. You can grab that and manually move it to the range you want. It looks like you can go to 1300 yards but it will only move to 1100. Make sure you hit the send range/bearing button after you do.
