CASE STRETCHING PROGRAM

[pjifl]

I WROTE A PROGRAM TO HELP WITH WILDCATTING AND REAMER DESIGN.
It has been tidied up and is now available.

The inter dependencies of various parameters makes it difficult to fully visualize how a cartridge case may be deliberately wildcatted by changing its dimensions when it is fire-formed in a different chamber.
This program will help immensely.
It also calculates angles matching the points if someone wants to make a reamer. There is far more to reamer design than this - but it is an essential step.
Either accept the default case which is approximately a 308Win or enter values matching some other case. Help notes are included. Maybe I will fleece this out and add to the program, but at the moment it is very useful.

You get this with some BUGS. Please contact me if you find any serious errors.

This program may help settle a dispute on case stretching rules and point administrators to a sensible way forward. I will add some notes on this eventually but for the time being, you can investigate case stretching yourself.

Download the zipped file (bottom right on screen). It is suggested that you Unzip and place the entire created directory in C: drive as C:\CASES. Then run the program 'CaseShapeZ.exe' within this directory.
