Bomber-Hunting
I set the 13mm all the way out to D650. Use them as "lining-the-target-up" shots or simple "scare-away" shots. I set the Tater to D300. If you make your approach right and heading at high speed at the edge of the controls, shoot the MG at D800-D650. Once you hit D500-300, fire the Tater. If you miss, this means you were either going way too fast and you were shaking, or it's your aiming, not the convergence. If you happen to take rockets, pull the nose up about 2x or 2.5x when you would shoot the Tater at D500-300, less if you're closer, and fire. Don't be afraid of collisions, one rocket should put them out of their misery. Just watch out for drone warping.

I set the 13mm all the way out to D650. Like above, use them to line the target up or to get their attention. As for the Tater, put it D250, since you only have 60 shots, use them as close as possible and use 3 at a time (max). Don't worry about pulling your nose up, because at D250-D200, you're so close that you barely need to.
Good luck.
