    As best as I can tell the 7mmWSM shooting a Hornady 162gr Amax with a bc of 0.625 would have to achieve 4000fps and it would still have a wind drift of 1.1" at 100yds in a 30 knot wind. At 1000yds this load would only have about 138" of wind drift which is approx 70" better than the same bullet at 2950fps. That is a real advantage.
    My 338 drifts less than an inch in a 30 knot sidewind @ 100 yards. 300gr (.450 g7 BC) @ 3,275 fps.

    If it's not a first round hit you need to practice more
