Thanks for the info guys, but I still don't know how far the guns shoot. I don't think I explained my question well enough, so here goes again. Lets say I have P-51 and I'm closing on an enemy plane's 6. I know I should get as close as possible but...I'm at 800m (just for example) behind him, can my 50's hit him, or am I just wasting ammo? See where I am going here? I'd like to know this for each plane because there is always the time when your best (or only) shot may be at some long distance and you will need to know if you should even try to squeeze off a few.
