No comment. Really.

As an example, a short concentrated burst of 6 50" can easily cut the wing of a B17.

About 20mm guns, as far as I understand, the effects of a mine or HE projectiles are mainly based on the explosive contents, so, range should not be a primary factor determining the destructive power as far as you can hit the target with enough E to trigger the BOOM.

I read a lot of times (not confirmed) that AH models a mixture of explosive/AP for each gun hit. So, even being explosive power the same for any 20mm gun, mixing always that with AP (lets suppose 50%/50%) will give a definitive destructive advantage for projectiles with better kinetics.

True of mine shells, less so of other HE types which also used kinetic energy, especially if they had a delayed-action fuze.

I wonder if this is the reason why Hispanos are still the best anti tank gun in the game.

If they were firing AP rounds (which the British never used - I don't know about the USA) then the Hispano would be better at hole-punching through armour than just about any air combat (as opposed to speficially anti-tank) gun.

The only exceptions I can think of would be the VYa-23 and of course the MK 103 and NS-37.

Didn't the British use AP ammo for their Hispanos relatively early in the war because they were having trouble with the fuzes on the HE shells going off too early?

When did they fix that problem?

They used a plain hollow steel "ball" round (basically a Target Practice). However, the fuze problem was licked as early as late 1940. The ball round stayed in the ammo belts alongside HE/HEI because of its semi-AP performance until replaced by the SAPI in 1942.

Like the Ostwinds 37mm was...

Brady:

I am curious. How did you determine how many rounds you hit with?

I was close enought not to miss, and we did it several times, and took an average.

I also used the ammo counter.

We tryed doing it on the runway but I couldent get the planes lined up well enought to do it relably.

Just give it up Brady.

Cant, although I know what you mean:)
