Default Which takes more wind

Which takes more wind a jsb express at 7.9 grains traveling at 810 fts shot from same rifle say a steyr and also at the same distance say 40 yards or does the 8.4 grains exact traveling at 785 fts take less wind. The wind is a full value wind at 10mph. Any ideas anyone ????????????
