    Excellent thread .

    Of specific interest to me was how this representation
    really shows how the impacts at various ranges get closer
    with heavier bullets in a 16 inch barrel .
    Specifically with the 50 yard zero .
    I'm still in the 50 yard zero camp for Aimpoints .
    I've considered the 100 yard zero many times but
    keep coming back to the 50 .

    Does any one have the math as to how much the
    impacts are changed with an optic versus irons ?

    Specifically for Aimpoints with a lower 1/3 co-witness
    as they would be slightly further from the barrel .
