"Is the bomber AI set to making only "real life" rate of turns and am i flying to unrealistically"
Yep, and Yep.
Go easy on the rudder and elevator. Bank the plane, add just a touch of rudder. Easiest may be to try it in External view, so you can see all 3 planes ahead of you. Just bank the bird and hold it there, if you start adding too much rudder you'll see them start drifting. If that happens just hold the bank but no other inputs, and they'll drift back.
They are not fighters, slow and easy is the key.
