I recently wrote an exterior ballistics calculator and released it under the GPL as free software, with source code.
I post it here in the hopes that some other people may get some use out of it.
http://www.sourceforge.net/projects/balcomp/
or
http://www.nerdulator.net/ballistics/
The program generates numerical solutions to ballistics problems based on the standard drag functions G1-G8. I wrote it for basic load analysis, with a very keen eye on the solution accuracy. It has special facilities to make it easy to get the data out of the program and into other programs,Excel, Matlab, OpenOffice, etc) for making your own range cards and click-sheets. It also computes windage, shooting angle, and atmospheric corrections.
I benchmarked it against several commercial software releases which I have acquired over the years, and it is spot-on for accuracy in both elevation and windage,G1 drag function).
It's only a couple weeks old right now as a public software, and is still evolving quite rapidly. So if you use it and like it, but want something else added to make it easier to use, then please let me know.
Here's a few screenshots of it in action:
