Re: About WW2 fighter aircraft firing power
Rob, there are books which explains the effects of different HE, API etc rounds and those effects are very significant, that’s why ball rounds were not very common late war years even if they many times had better kinetic energy than HE rounds.
On hitting, you leave away very important factor, gravity drop. Higher muzzle velocity means flatter flight path and made hitting easier.
And some WWII aircraft guns had muzzle velocities as low as appr 520m/s.
