It is easily understood and accepted that a bullet exposed to wind resistance will gradually lose velocity, and at or about the point of becoming subsonic the bullet often destabilizes and accuracy falls apart. What I have never heard is any data on rotational force and if that force is maintained or gradually bled off as the bullet flies.
Maybe my explanation doesn’t make sense...
a bullet leaving a barrel at 3000 FPS from a barrel with 1-12 twist rotates at 18000 rpm at the end of the muzzle. At 200 yards down range, is is still at 18000 rpm or has it dropped? I would assume so. Is the loss of spin rate similar to the loss of linear velocity?
