now if we said the bullet is a cylinder for the sake of simplicity, (7.98E^(-5))m^2
take the density of air...1.225kgm^(-3)
And if I knew the drag coefficient we could figure out how much heat that bullet is really experiencing from the force of drag on it...

I got it down to 9056.3*Cd=ForceDrag
I dunno bout you but...air friction is a b*tch.
I think there comes a point where the bullets would just vaporize.
Now I could be wrong and the coefficient is so small it doesn't matter and my limited knowledge might not actually know if it really works like that...
EDIT:
....I'm over thinking things =w=
Still....I'm pretty certain that there would be something....I just don't know what though...
