Steve, what's your averge rounds per kill w/ the 50 cals? The way I approach my target only give me .5-1 sec of firing time before I gotta pull off to avoid the collision. Which is why I prefer the D-9 over the P-51. 90% of my sorties I hit my 10 kills part by the time I hit 200 cannon rounds remaining on the D-9. Average about every 100 rounds = 3 kills and 1-3 assists.
I can't do it w/ any planes that have 50 cals, or Hispanos. I tried earlier today flying a tempest, I do the exact thing I do w/ the D-9 but my shots are off. I'm guessing I'm used to the MG151? (cannon for the LW birds). I'd get on the enemy's high 6 about 600 yards out, approach to 300 and fire til i get to 100 and pull off. Which bring me to another point, of why I've been flying the LW over any other country fighter. I've got the aiming and projectile rate of the LWs gun and I don't want to mess it up w/ different gun.
