I dont know if it has something to do with the polluted sky conditons or what.
Upped a yak got 200 off a six, fired the whole load and what should have been kills was no hits.
Upped a 47m and got 200 off a 110s six and had not hits what so ever.
Upped a ki and shot at a typhone less than 200 while it was stalled and not hits.
Upped a ki again, 200 off a f4u-c stalled in front of me, no hits...
I fly the ki mostly and these were not even hard shots to get, normally they should have been kills.
Others are complaining of the same thing.
