In my erperience, the advantage any magnum has in wind deflection is less than it has in trajectory. Wind deflection is directly correlated to ballistic coeffciecent and muzzle velcocity, but most 7mm and .300 magnums only have a 10% or so increase in muzzle velocity over most "standard" cartridges with the same bullet. Hence, wind drift isn't affected all that much. ALL bullets drift in the wind, and more than we would like.
