I have gallyhorn, but I actually aim it. The tracking is useless to tell the truth, only seen it work once. When crota moved as I shot it turned and launched into her face. I don't need it tho, I'm good at aiming. Only time I was upset tracking didn't work was when I was close to soloing phogoth on weekly, I used my last shot at his head, and he bent his head at last second and it missed.
