After watching this quite a few times it seemed to me that your rounds were falling short for the most part

Though when I watched from the cockpit view it did seem that they were in fact going "through" the Tempest.
The only suspicious thing I saw was when you followed him and made a shot inverted and that missed..and a hit I saw from 200 right before he broke away and it did no damage at all.
I do have to say I was stunned the first time I watched it though.

Edit : I've never usually had problems with the bullet stream going directly through the target so often...I've only on rare occasions seen the round connect and do no damage when Im in the K4 or G14...unfortunately I dont have those filmed..
