In SF2, the air to ground targeting information presented to the virtual pilot on the planes using a bare AG gunsight (not a full functioning HUD), are primitive, inflexible and almost useless for proper air to ground stores delivery with the gunsight itself. If the gunsight was providing a real time adjustable gunsight pipper angle, the result would have been very different. Therefore you need to use either the hit-or-miss WW2 (or earlier)-like techniques perfected by the users, such as those in the video, or use alternative cockpits and models available in mods which provide a better experience of the early/mid cold-war era. You can try Ravenclaws F-4E/F Cockpit models with the CCIP (Continuously Computed Impact Point) function implemented, or Yakarov79's F-104G's. Both these alternatives provide a highly pleasant visual and functional experience. Bare in mind that the computed bombing solutions of the said and similar mods are not 100% historicaly accurate, due to SF2 limitations and because the real early F-4E & the F-104G's bombing avionics were presenting CCRP -Continuously Computed Release Point rather than CCIP, and because this targeting info was really presented on the Radar scope, which in SF2 is underutilised in air to ground targeting. However, the mentioned mods and all other similar, provide for these cold war planes a repeatable, more enjoying and at the end of the day much more accurate solution than the hit-or-miss alternatives. So I think the better solution to the problem mentioned in the first post is found in the downloads section.
