    There is an Excel file on Lilja's website that lets you play with all the bullet parameters and get calculated BC. It uses McCoy's formulas.
    No ogive (wadcutter) would be worse than no boattail (flatbase)

    Ogive and meplate size (how sharp the tip is) affect it more than the boattail. But it all adds up....

    If you're concerned about BC then you've gota have it at all.

    Accuracy is another story entirely.
