Any reason to use Ball Ammo?

[Roblex]

Thanks for all that. The only thing I am still not sure of is,you say ball does a lot of damage to ailerons & even engines but you
also say that the game does not model the deflection problem with AP so surely that would mean that AP is always better than ball? Ball
can only damage things by making holes and AP would make as big a hole plus it would also do more damage to harder structures that ball
does not. Is there a flaw in my logic?
