Hi Beagle,
I have of course heard of various folk over the years whose ability to use the cannon effectively were simply amazing.
As the unelected voice of ‘the rest of us’ - even with a very accurate aiming group provided by the excellent APG-79 on the Super Hornet - I would humbly suggest that the ‘single shot kill’ with a cannon is never going to happen. A ‘single shot hit’ in anything other than a stable tail chase like scenario would (for the likes of me) be a miracle.
I think the ‘small number of hits managed out of a 100 round burst at fleeting target’ is probably more likely.
The approved technique is to recognise potential passage of target through ones HUD. Select gun. Trigger down. Make lame attempt at leading target. Over control a little. Watch target flash through. Release trigger. Watch tape later.
