Yes, I am.
As you said, anytime the gun line is not aligned with the relative wind, the bullets tend not to go where the pilot thinks they will.
Some of this is due to aerodynamic effects (the rounds aligning themselves with the airflow) and some of it is due to vector summation (the velocity vector of the round and firing aircraft not in alignment).
It all adds up to an impact point that is not where the pilot thinks. The corrective action is for the pilot to "overlead" in the direction of travel to bring the impact point back to where he wants.
The problem with this technique is that rudder control is far less precise than pitch and/or roll input. Our size 12 footsies are not quite as discriminating on the pedals as our hand on the stick is (for any number of reasons). This may not be so significant in sim HOTAS setups where rudder can be modeled to the stick twist grip or throttle switch/knob.
In RL, every now and then I would hear about someone "kicking the rudder" when strafing to improve his aim. Then I tried it one day...being young and foolish and willing to try anything that I heard at the bar.
Well...I only did it once! I sprayed rounds all over the place and came away with the firm conviction that aiming properly in the first place was a much better gameplan.
This aiming error is present in all unguided weapon delivery...guns, rockets, or bombs. The sight "lies" to you regardless of weapon type.
One minor correction. The gunsight in AH (or any other sim or in RL) is not the "boresight". The gunsight aiming point, sometimes called the pipper, is the convergence point. The "boresight" is just that...the extended line of the barrel into space. The pipper is set to indicate where the path of the projectile intersects the desired range and convergence and is a function of time of flight/gravity drop. Usually, the boresight of the gun is therefore "above" the pipper. The process of setting this up is called "harmonization". The term "boresight" comes from the optical device that is used to literally look through the barrel when aligning the gun during the harmonization procedure. The optical device is inserted into the gun chamber ("bore") and then looked through (sighted") at a fixed target at a predetermined distance in front of the aircraft.
