Gun pipper not matching shell trajectory

[Uhu]

Hello!

Having just returned to one of my favourite sim games, I quickly encountered an annoying issue again.

How are the sight line of the pipper / LCOS / the "aiming dot" for gun shells and rockets boresighted to the actual flight path of your projectiles? How could you modify these parameters?

Two examples.

1) Nato Fighters 5, RSR phase 2, German Tornado IDS, e.g. on a CAS mission. I often try to take out the opposite CAS, don't like having my own tanks strafed. But I have to save my 2 'winders for those Flankers soaring above and hunting for any mud mover down below, so I'd have to use the gun. The plane has an LCOS as TRUE in the COCKPIT.ini, but the pipper is waaay to much off from the actual shell flight path, starting from the center of the HUD from the plane. N.b.: the caged AG sight is well placed on the bottom of the simulated HUD plate.

2) Stock F-100, LAU3-Hydras on the outboard pylons. No matter in what angle I'll dive ob the target (albeit I tend to make only really shallow dives, max. 20° below the horizontal...), I need to take aim with approximately the 6-o'clock-diamond of the sight to have a better chance to get a hit, shooting from 1.2 to 0.5 miles distance from the target. It visually seems that the pylons are already somewhat depressed below a true 0° horizontal plane (this is IIRC also the case on stock F-105). On the other side, the guns for the Hun seem to be really well boresighted to the HUD aiming line, almost better than every other plane I'm aware of (either stock or 3rd party).

And more, the LCOS, even with radar lock, is often off the true projectile path for me, so I wonder if the refresh rate for the lead computing is low or takes a long time to adjust for a G loading or a fast changing target range. Possible situation: 6G turn, target 0.4 miles distant, closing with 140 knots, I am in his 7 o'clock and a bit less than a second in the turn - the e.g. M61 shells that possibly down the opponent seem to be never those fired while the pipper was over the enemy but more likely those I fired while pulling farther in his turn and having the gunsight visually around 3 plane lenghts in front of his nose.

How and where (xxx_COCKPIT.ini?) ist a bad boresight to be fixed? Any hints?
