Great tips above.
I have one thing that I do with the D Hog in terms of convergence that I found works very well.
I set the convergence of the 3 sets of fifties at progresively longer ranges starting at the outside set and working in. I set the outside bank to 325, the middle bank to 350, and the inside bank to 375. I find this lets me hit hard at any range between 300 and 400. The additional benefit is that when you do it this way you "cross the streams" from each wing bank at a closer point, say around 150, so you have mini-convergence points for each wing in close. This allows me to keep my convergence a bit farther out, and still have good killing power for those up-close and personal shots.
This is what works for me, but it is best to do your own testing if you can and see what works best for you. Experiment with shorter ranges and try holding your fire more if your gunnery percentage is very low. You will find that in the course of testing, you will learn a bunch about your gunnery as well. Grab a trainer in the TA and we'll play targets for ya.
A note about zoom view: Don't use it to deflection shoot, use it to see a target's aspect at range and to make those long dead-six shots. The best use of the zoom view is to see what direction a target is moving at longer range to help setup your attack. I'll also use it when somebody is running from me, and I need to take a shot at longer range on that very thin dead-six aspect ange. Don't use zoom for any kind of deflection shooting as it throws your judgement off and you will be more likely to miss IMHO.
The D Hog is a real challenge, but I find it very rewarding to fly. One benefit of the D is that it has an absolute PILE of ammo. That is good in the sense that you can spray some ammo around on those low-percentage shots without worrying about it too much. It's bad because it gives you bad habits and you find you will be taking shots you shouldn't, and burning E when you do it. If you want to improve your gunnery try flying the Spit for a couple of weeks and use nothing but the cannons. Then go back to the D Hog and be surprised at how many kills you can get in a sortie.

Always got me through so far
Well they can ship me all over this great big world
