anyway, what weapon ya use to kill 3 ju88s

me lim ammo, fw190 wth 30mm mk108s killed 5or6 of them, same mission wth mg15120s, only killed 1 of them and was masacred out o the sky

Thats easy, do NOT settle in behind them and snipe you away.
Rather make attacks from all angles, everything else than straight behind does the trick.
My favorite (and always working) method is to get above the bombers and come in from straight above or their very high 12 o' clock. Only works with 20 mm's and up of course.
With MG's just get above and in front of them and come in high or low, slightly from the side or head on.
With slower fighters like the Hurricane its gonna be difficult to get in front of them of course, so there a side attack should suffice.
