Using my project sbts-aru. I have a test network of recorders here in the Netherlands with collaborators. At 22:15, around one hour after sunset, so definately dark. Two shots from a shot gun. I didn't hear these, read the message the in morning and can clearly hear them in the recording. But was able to localize to a road intended for walkers and farm travel between fields where a lot of rabbits are, where you can get a quick getaway via multiple escape routes.

Was able to localize, likely to around within 20 meters, with just three recorders. One of the recorders was almost 3km away.
