If you can't get a kill with 800 rounds of the strongest 20mm in the game (C-hog) or 3400 rounds of super-accurate 50cal (P-47s) or 2400 rounds of 50cal (F4us) or 780 rounds of 20mm AND 950 rounds of 13mm (basically 50cal) in the 190A8, or 360 rounds of 30mm (262) or 900 rounds of 20mm in the N1K2
If you can't do any of those, I'm sorry. You fail. Turn in your joystick and go play quake. These are the levels in-game NOW, with 1x multipliers in effect.
If you suck so bad you can't get a kill with enough ammo to demolish your hometown, no amount of lame-arse gimmicky crutches (i.e. unlimited ammo) is going to help you.
No.
Fail.
Might I suggest internet checkers?
