Wind drift

[Almer Fudd]

Is there anyone who can help me with question.
This weekend I was Mulie Hunting in some VERY strong winds (likely 70-90 KPH).
We spotted a decent Mulie Buck at 250 yds, wind was 90 degrees (broadside).
I'm shooting a .270, 150 gr. partition pushed by 57 gr. of 4350 (pretty hot)
I didn't shoot due to the strong wind gusts, early date and the buck was short about 30 inches.
My question is what would the wind drift be on this shot?

Thanks
