When did USA naval 20mm an-m3's get so horribly bad (again)?

Btw… he showed us that he got late shots with AN/M3(barely hitting his targets), on wing mounted guns,… but he seems to lead Nose mounted guns pretty easily,…

Could it be related to “Skill issue”

there are no nose mounted AN-M3 guns
This has been datamined, realshatter was back when i made the post.
And it’s funny cause i’m usually better in wing mounted cannon planes than on nose mounted cannon planes.

These guns have become near useless against the buffed bombers. Yesterday I was playing squadron battles and I was trying to shoot down a il-28 with my F7F-1, I had to fire nearly 600 rounds just to damage the engines and tail.
Even against fighters the rounds were doing very little damage. I was using universal belt since it was squadron battles.
