    Wonder how Bryan obtained RT/R
    I wouldn't wish my tedious method on anyone.

    First step is to mount the bullet in a lathe and indicate the bullet ogive with a dial indicator every 0.025" along it's surface. Then input those coordinates into a computer program that calculates ogive radius and length. Then calculate the radius of a perfectly tangent ogive of that length. Finally, divide the 'perfectly tangent' ogive radius by the measured ogive radius. The result is Rt/R.

    I'm sure there are other ways to skin this cat, but I've found this method to be (more or less) reliable and repeatable even if it is a little maddening.

    -Bryan

    Re: A small contribution to the shooting community

    I'm glad you answered that one. If my memory serves me well I did not read
    that in the book.

    It's a pretty awesome sneaky way of doing it. I like that!

    Thanks!

    Dear Folks,

    The OGW box was not calculating the varmint weight correctly.
    It was, of course, my bad. I also added to the info section seen
    when you right click on the underlined portion.

    just download from the link and replace the file.
    My thanks to the person who caught it and e-mailed me. I don't
    know his name. "I have a strong feeling is a 'He' ".

    Please excuse me for the inconvenience.

    Sincerely,

    Javier Moncada

    The Lord willing, I'll be adding more to it and make it even more useful.

    Re: (UPDATE) A small contribution to the shooting community

    A new tab page has been added. This concludes all of the book's formulas.
    A photo was also added for now to occupy empty space.

    Due to a small change in the .exe's name you'll have to delete the old one
    since it will not be replaced.

    Your input is appreciated.
