Skuzzy moved this to the "help and training" forum! I think he's trying to tell ya something Dolby 
It is a legitimate question, but without a film, it is simply too broad in scope to accurately answer.
If you want a general answer. Each round does X amount of damage to a component. Once the component reaches X amount of damage, it fails. A wing is comprised of several components. Is it possible to hit it and not do critical damage? Yes. Does a 30mm round do more damage than a 20mm round? Given an equal parameter of velocity, then yes it does.
With a film, we can tell exactly what was hit and how much damage is done.
