The entire argument of burst mass makes no sense, especially when it’s one second burst mass (Look at the video of the P-80 above) In any match. You’re not going to get a full second of burst onto a singular enemy unless they are flying completely straight and unaware or AFK.
The majority of the time, you’re going to get glancing blows that do nothing in deflection shots. They achieve no major loss in lift nor do they heavily affect the flight characteristics of the aircraft.
Compare this to a single 20mm being able to snap a P-51C in half. The P-51C snaps in this location. Making it where cannon rounds magically have the explosive filler of bombs. This why the ‘ammunition amount’ argument makes no sense. You can literally 1 tap aircraft, if you run out of ammunition. That’s your fault. I regularly go in the Fw-190 A-1 and I will point-and-click-adventure La-5s, P-40s, Ki-43s, Ki-45s, P-38s, and even P-51s and P-47s with one round from either cannon smacking one of their wings instantly splitting them into two or magically combusting their wing tip to pieces, and vice versa for most other country’s cannons
second clip a B-17 is being peppered by a Bf-110 G-2 yet the wing isn’t mysteriously flying off nor is the tail splitting in half. I wonder what gun the Bf-110 G-2 has?
According to war thunder. 1-2 hits is what kills the plane. Lol
