Ballstic equation
« on: January 20, 2004, 03:50:52 PM »
Does anyone know the formula for computing bullet trajectory?  I want to be able to put the formula into an Excel spreadsheet so that all I have to do is enter the ballistic coefficient, velocity, bullet weight and be able to calculate the trajectory.  I know that there are a lot of different programs out there that will do what I am looking to do, but I would like to have it on my PDA.
Any info would help, Thanks

The program that I wrote years ago used a number of recursive calculations to compute the decelleration and fall of the bullet from the ejecta angle and reference it to line of site. I still have the original code but the interface is DOS and nobody uses DOS anymore.

Hodgdon, Lyman, Speer, Sierra, Hornady = reliable resources
so and so's pages on the internet = not reliable resources
Alway check loads you find on the internet against manuals.
NEVER exceed maximum listed loads.

Oxnam,
Before you think it's that easy, do a search on "ballistic equation" or terminal ballistics or the like. Sub sonic, trans-sonic, hyper-sonic changes the constant. don't think it can be boiled down to an excel spreadsheet unless you're only going to deal in a narrow velocity range. Then you might be able to. here's a good link to an explanation: http://www.steyrscout.org/extbal.htm
