I was again learning stuff about shooting and came across the question that had one .22lr shooter had.
The ballistic programs give less wind deflection for rimfire ammo with less speed. And this applies even when both bullets have identical weight!
Here is the link I found which explains this phenomena: http://www.gunsmoke.com/guns/1022/22drift_cross.html
The reason to this is that as we know, bullet has hard time passing in the transonic region and that is due to air resistance growing over double of the resistance under or over the transonic region. (Insert fancy picture here)
And I had never thought that the same air resistance would of course apply to wind effects too!
