Normally the engine is moving fast through mostly clean air with oxygen content. What comes out of the gun besides the shell is high speed burned gunpowder and burn products with no free oxygen.
It is not forced into the engine at such high relative speed which reduces the pressure in the engine and it does not burn the engine fuel which then only cools the intake.
If *enough* of that happens, the flame goes out and right after that the air coming is again at high speed and doesn't relight the air-fuel mix so easy.
The burned powder solid products don't do the compressor blades much good and remember that they are burn your face off hot.
Don't hose ammo with those planes?
