Whatever speed it's going, once it leaves the end pf the barrel it's subjected to 10m/s^2 downwards acceleration in addition to whatever air friction is slowing it down by.

How far does a dropped object fall in 10 seconds? That's more-or-less the vertical amount you need to compensate when aiming (the height of the Shard is about right)

Even with modern measuring instruments capable of dynamically measuring air movements along the path that's a hellaciously impressive shot.
