Can confirm this is a problem, both on Alliance side and Horde side using the same type of guns in the Horde version of this quest. Except on Alliance side it’s even more difficult to complete.
Same here. Decided to dust off my DK which I haven’t played since Cataclysm, decided to do Legion leveling, stuck at cannonballs that blow up in your face in Greymane’s Gambit P2. I managed to get 27/30 firing at the low-hanging ones, patience ran out after several minutes of not managing to get any more than that.
Like Nazhara, I am also stuck at 27/30. The bats don’t respawn, so after you kill the ones that you can, you’re out of luck. I’ve tried reaching them with character abilities and I’m unable.
As a quest that basically unlocks a major Legion questline, this should be made a priority.

I am also having this problem. I got 25 but can’t seem to get anymore and my ranged attacks aren’t able to reach them even at the highest points of the ship. I’m surprised this has been an issue for so long. I’d really like to complete this soon.
I sent a ticket to Blizzard about this and they said there’s no work around unfortunately it’s not fixed. But they did finish the quest for me so I was able to turn it in! Definitely worth getting ahold of them.

I just did this quest while leveling. Once you get on the ship, use bow as 12 o’clock. Fire the gun between 1-3. There’s individual ones that fly from 12-4, every 10secs or so there’s a group of three that spawn and you can hit them.
This isn’t the only gun doing this, even turrets in shadowlands (Ardenweald is main culprit) are broken.
It’s as if there’s an invisible wall that blocks the shots, allowing you to fire in a certain spot. I literally had to fire backwards on one cannon because that’s the only way the “bullet” would come out.
I’m glad it helped! Happy gaming 
right lol wish it was a joke.
they’ve got time to censor my language but not time to just allow players to skip that part of the quest until they fix it
