T34/76
I hesitate to mention this very minor problem as I don't know if it is a bug or it's supposed to be this way. However, for a target that gives hits at 2800 yds on the sight with AP loaded it hits at 2700 yds when you switch to HVAP. Since the sights change when you switch AP to HVAP, I presumed they are each calibrated for their specific shell, in which case you'd expect to be able to hit a target at 2800 with both sights reading 2800. The two sights are not consistent with each other.
