What are you trying to hit with them? They can hit Gjall, although they do miss sometimes, which is odd, since Gjall are huge and, and the ballista is pretty short range. Of course, they're not going to hit bats. I don't know about Drake, but Drake shouldn't be a problem unless you're in the mountains.
