I beleive the standard round for the 0.5 inch browning used in aircraft was API for both the U.S. and Britian. Tracers were being discontinued in fighters by late 44. Tracers in our game are helpful to micro adjust your bullet stream once you have contact or while missing by a narrow margine.
Penetration at 0 degrees.

15 inches of packed sand at 200 yards.
Note: I dismatle tested an A6m5, HurriC and Brewster from 100 yards with a P51D.
I started with the outer wing panels and rear of the plane aft of the wing trailing edge. Shooting those areas is futile and takes a while to cause any perceivable damage with 50cal. I expended hundreds of rounds in single taps to eventualy remove the wings and tail surfaces. I was still able to place rounds aft of the wing root and the planes kept flying. A single tap forward of the wing root killed the aircraft.
In a additional testing tapping the trigger aiming into the wing root started a fire. Shooting into the fuslage forward of the wing trailing edge causes oil leaks, fuel leaks or kills the pilot.
