A small contribution to the shooting community

A SMALL CONTRIBUTION TO THE SHOOTING COMMUNITY

I have created a small application that uses most of the equations found in
the book Applied Ballistics for Long Range Shooting by
Bryan Litz
I find it very useful and it sure is a great tool to get very close values for BC7, BC1
from measurements of a long range bullet. There are various equations that are
fun to use.

It's a very simple straight forward application that would be useful for some of the
long range shooting addicts. :-)

It's only for the Windows Platform, unfortunately.

Download the zipped file named "readme.zip". When you unzip it there will be two
files, one is the ".exe" application and the other one is the readme.text file.

Please read the short readme.text file before you run it.

You don't have to install it; I recommend you drop the ".exe" file on your desk top
and your ready to go after checking the readme.text file.

    Changes have been made to allow the application to run
    in smaller resolution screens. Just download it from the
    same link above and replace the old file with the new.

    Mikecr, good question!

    I will tell you how I do it.

    I know is a value between 0.5 and 1.0 by studying the bullet diagrams on

    Bryan Litz's book, I can get pretty close at guessing the number. I have tested

    my self and as the book states it, it can easily be done. It also states

    how difficult it is to calculate it. You might find some info. on line that would be

    useful. What we need to keep in mind is that we don't have a whole lot to

    err with, we'll go from 0.5 to 1.0 being 1.0 perfectly tangent ogive radius.

    By looking at the bullets diagrams and seeing their Rt/R ratio values and how

    they change in value as the bullet ogive changes you get a pretty good idea of

    what you're doing.

    I know I'm not giving you what you want to hear, but with a bit of practice

    one can really get close to calculating them BC7s.

    There is a whole lot to learn about that stuff!

    I'll keep looking.
    May need a tool(laser mic) & software to derive it...
    Wonder how Bryan obtained RT/R

    Note to all:

    Please know that I'm not in violation of any rights what's so ever and that Mr. Litz,
    Bryan Litz, does not condemn the release of my small application linked for
    on the top post.

    Please read what Mr. Litz said:
