    BC is not a fixed flat line number, its a curve, hence why Sierra supply banded BC for velocity
    The RUM speeds with the 168 are outside of what most would consider 'normal' range
    However, you would need to be around 0.54 to get the drops you're talking about
    Presuming its 30 cal

    Based on your data, I work it out on my software to be ~13 MOA @780yds ignoring wind
