Yes it is for fun but in some weird wisted way it makes sense.

The the aircraft and the bullet have different vectors. It takes time for the bullet to pass through the skin of the aircraft. During that time the aircraft moves (about 3.5mm from my rough calculations). Therefore due to the momentum of the bullet and its physical properties that make it want to continue on its path, the holes should not be round.

What I did not factor into my calculations were the acceleration imparted by the skin of the aircraft onto the bullet, nor the fact that the .303 bullet was designed deform and tumble after impact to impart it's energy to it's target, both of which goes towards my original statement.

It's times like these we need Raaid to explain things on this forum!!!!!

Cheers!

This makes sense. And again, is a matter of angle of attack (bullet and plane vectors and or trajectories).

And no, I don't think mass of bullet, velocity, skin hardness and angle of attack (deflection) will ever be modelled in SoW...
