Player and plane roster...

I use the P-51B with its 4x0.50 mostly to hunt heavy bombers with great success, so they can't be that bad

I have been flying it a bit as well, the only time I have problems dropping a plane with 4 50s I would likely have the same problem with any gun(the bigger gun may damage more, but it's still harder to aim it)

want a high hit percentage...fly a 202 for month....some of my best hit percentages were due to that thing.  have to be close and land  some rounds to get a kill.

It simply just takes me 1 or 2 more passes to take a plane down if I don't get at least a 1 second sprey on them. If I only have small burst moments of shooting, I generally don't do enough damage each pass to take them down all at one time. It's difficult to fix the convergence for me because I shoot at all distances.
