Real life guns did not have trouble killing planes beyond ranges of 300 yds, the trouble was hitting the target. Most of us have been firing at simulated moving targets propably more than any pilot in WWII so our hit percentage is much higher than were in real life and we can hit targets far away which was not usual in WWII.
Bomber guns seem to be more effective than the ones in fighters but that might be because they don't have as much dispersion or concergence problem.
