I made some changes to help my aiming and it is paying off. There is no doubt now my aiming was lame not the 38's firepower. I am pushing myself each day to improve in the P38. I went back to a mustang for a pickup mission, and realized I am hooked on the 38.

And to think, I was so close to going to the dark-side not long ago.

After Latrobe's FOV post and with a Squad mates suggestion, I changed my FOV setting to 93. At y'all's suggestion, I switched to the large ammo load out and switched the MG to the trigger and the canon to the secondary. At 93 on my screen it pushes you in a more realistic view and somewhat of a constant zoom. With the the TrackIR it is perfect.
It took awhile to to get use to the new trigger arrangement but it has paid off. I can tickle a red guy at 1000 out enough that he will stop a run giving me a good shot on his or her turn. I can also take a few low percentage shots without using up my canon. if you can get use to a two trigger mapping with the larger load out, it might be worth the missed victories up front while you train another digit.
Thanks again for showing me the way to fight with the P38.
