I am by no means the best at doing this but I figured I'd try to help some other guys with this type of shot that might be having trouble with it. I used to suck at this a few months ago when I was getting familiar with the german rides but practiced and got better.
Your traditional situation in a 262:
You are coming in on a bogey going straight and he turns his wings and breaks one direction. The instinctual thing to do is to track his turn with your gunsight and by the time he gets into firing range he is out of 30mm gun solution. You fire at him, undershoot and he flies off and you continue straight kill-less. If you could connect on this shot consistently you will at least quadruple your average Kills/Sortie in the Me262.
Here's the trick: Once you see him tilt his wings to turn, you immediately turn your jet as far out in front of him as you can visualize. It's also a good idea to use your full rudder in the direction of the turn to get your nose even further ahead of his turn path. You want to be visualizing where he will be in five seconds. To put it simple as moot and scotch told me, you almost want to try to ram him. Once you get your nose way out there, it's a waiting game as he continues to turn into your gun solution. This gives you about a second to line up the shot and fire on time. Hopefully you connect with a tater, this is how it's done. 95% of the battle is won in the shot setup, not the actual shot itself. Set yourself up for the easiest shot possible.

You want to try to get that shot in the range of 100-200 yds. Hope this helps anybody that has trouble with the taters as I once did. salute
