    I'm wondering if different bullets drift more or less or if there is a huge difference.

    308 win

    178 hornady hpbt
    Sierra 175
    Nosler 175

    All bullets @ 2700 fps
    My atmospheric conditions
    1000 yard 10 mph wind drift

    Hornady 178 HPBT - 7.3 MOA
    Sierra 175 HPBT - 8.2 MOA
    Nosler Custom Comp 175 BTHP - 7.9 MOA

    Things can change if you use say the 175 RDF, TMK, 178 eld-m, and so on. So yes, different bullets can and will change significantly depending upon B.C.

    Also effected is retained velocity, energy, and bullet drop.

    All numbers attained by use of Applied Ballistics app.

    Ok thanks, because I've always wondered if my hornady match 178 hpbt was more easily pushed around by wind.

    Keep in mind, this is all based on the same velocity. If you haven't chronoed your loads, that can also change things. According to the ballistics, the Hornady should have the least wind drift if all bullets are starting at the same velocity.

    Some bullets are not pushed around by wind or can buck the wind better than others. The longer a bullet is in flight the more wind will affect it. So the better the bc of a bullet the less it slows down during flight and the less it will be moved from your aim point.
