I must disaggree Zygote.
I`ve hit fighters at range 1.6 as a gunner in B17.I`m yet to hit anything over 1.2 in fighter.
Besides in all books I`ve read about the LW fighting bombers over Europe,the LW opens fire from outside the range of the bombers`
machineguns,wich was as all these books state 800 meters.
It`s tuned up in AH ,so all the single bombers can have a chance in the MA.
BTW bombers SHOULD be desirable challenging targets,and fun to hunt ,but not certain death that we fighters have to avoid by all means.
I`ve killed many bombers,but sometimes they get me even if I set up a perfect attack.
