A small contribution to the shooting community

lightbulb A SMALL CONTRIBUTION TO THE SHOOTING COMMUNITY lightbulb

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.

Version 2.0.0.0 out

That's kinda a trick little deal!!! I haven't played with it much but I think it's kinda cool.

Thanks

bigngreen,

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.

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.

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.

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.

Eaglet,

I've been 'playing' with your .exe.

Quite fun and revealing.

Another question regarding Rt/R.

I'm working on a Swiss Navy project that is proving fruitful and your .exe has been quite a useful tool.

I took a Nosler bullet and measured the ogive length, BT length and meplat diameter.

I then used the 'Wild Itralian' method to determine RT/r which is, punch in values until the published bc was achieved.

Is this process reasonable and,

If the ogive is lengthened what does that do to the RT/r or does it make any difference.

BTW regarding being rewarded for your freebie .exe. Sneak a peek at Luke 6:38.

I'm sure glad to know some one is using it!!!

I was really cracking up when I read that! Roy, you have a great
sence of humor. I would have not thought of that... Thanks for telling
me! LOL

Is this process reasonable and,

The idea is using all the measurements to predict the "form factor"
and from there to obtain the BC7 . If you have Bryan's book, it has a bunch of diagrams with already done work, but if you get a bullet that you don't have info for, then by using his diagrams you can go through many of them and pretty much by comparing give your new bullet a Rt/R value that would put you real close.

If the ogive is lengthened what does that do to the RT/r or does it make any difference.

If it's changed in any direction, that means either making it longer or shorter your Rt/R value will change and your BC of course will change also.
As I understand it, when you lengthen the ogive, it minimizes the shock wave
which is a great contributor to drag. So definitely the BC would increase.

Thanks, I did; it's all the truth!

I hope that helps some!

Thanks Eaglet.

I'll order the book!

Knowledge is power. The book with your 'tool' adds greatly to that power.

Again re: your tool....

Version 2.0.0.0 is out!

Hope you all like it!
