Given the descriptions of wandwork we’ve seen in canon and in MoR so far, I imagine it’d be difficult to reliably hit anything person-sized past thirty feet or so. You can’t sight down a wand if you have to swish and flick (though a wizard’s staff with a telescopic scope mounted on it is a nice Discworldly image), so it should be about as accurate as throwing a ball—which is to say not very.
We know of at least one spell that aims itself (Flitwick’s) and area affect spells are possible (with a massive fireball it doesn’t matter how you aim).
Alternatively, take a potion of +10 accuracy or the equivalent.
You do have to aim it by hand and eye. You try hitting a human-sized target from a moving platform at 2km.

Felix Felicis may be the only potion that performs that function, and it’s sufficiently broken to be the Potion Not Appearing In This Fic.
Just find something that was made by using up a lot of accuracy. That should do it.
A target with nothing but bulls-eyes will do.
