BTR-82 and 82A need boresighting.

[MAJ_Fubar]

The TKN-4GA-02 sights on both the BTR-82 and BTR-82A are off by a considerable margin.  Both guns are firing about 4mils left and although the ballistics seem to match the range indicators, the aiming caret is either above (at range 0) or below (at ranges above 800m) the actual round impact. As an aside, are the range stadias supposed to move with the aiming caret and range wires?  Seems an odd choice if so.

Sorry, but I'm unable to  reproduce with wind speed set to 0 and gun dispersion disabled. And 4 mils point of impact deviation implies either wind or dispersion effects(lead scale  marks  have estimated 5 mils separation). Also note that sight does not compensate for parallax and drift.

Ok, with a bit more testing I figured out what I'd done, thanks for the info.
