TRAJECTORY

Originally written about 10 years ago this program has some unique features that allow one to trial and compare groups of shots using different bullets showing relative dispersion on a target. I know of no other program that does this. Oops - Brian Litz now has a program that does a similar thing, possibly better.

Some of the more modern web based programs are now more accurate in their predictions but this program allows comparative changes to predict difference in impacts on a target which is still relevant. Also allows one to compare the relative effects of other changes such as temperature, humidity, headwind etc.

It has gone through many iterations, some designed for small screen computers, now more aimed at powerful machines with a second screen.

I hope to modernize it sometime.
