Seafire,
Wind-drift is NOT dependent on bullet weight. Instead it's totally dependent on two factors, given the same atmospheric conditions: ballistic coefficient and muzzle velocity.
The 30-grain V-Max has just about exactly the same BC as the 40-grain CCI HP. But the 30 V-max starts out faster, so shoots flatter and drifts less in the wind at any range. I know this not just from theory but from shooting a bunch of different .22 Magnum loads in the field.
