I created my own config files that improve the accuracy
and increase the range of AI guns,
if you would like to give it a try your wellcome
it JSGME compatible

[AI Cannons]
Max error angle=
4 ;[deg]
Max fire range=
9000 ;[m]
Max fire wait=7 ;[s]12
[AI AA guns]
Max error angle=
5 ;[deg]
Max fire range=
1500 ;[m]1000
Max fire wait=3 ;[s]7
this is the section from the sim cfg that controlls AI guns
the highlighted figures are what your interested in I actually run lower angles of error in my game but this is what I uploaded.
you can open and edit this file with notepad.
hope this helps
