Is there a readme for setting up guns ?

[jamesdietz]

I'd like my guns to center at 250 ,which I think is 25 in settings,but do I need to do all the guns on say, the Hurricane by going thru each one ( next gun ,next gun-alot of time & work?) What do I do about horizontal & vertical settings? Finally can I set the loading ( type of ammo ) the same in each gun or do I need to do it gun by gun? Has anyone really figured this out & made meaningful changes away from default? I am fascinated by the possibilities but put off by the complexities...
Thanks!
