Federal Cartridge's Handy Ballistics Calculator

Click here to get the app. It is free.

This application for the PC has been around for years. It is now more stable and reliable than it was, early on.  By using a point and click interface, you can get the detailed ballistic behavior of any factory cartridge offered by Federal. A clever feature of this app is you can use it to compare the performance of cartridges you select; you get graphs and tables that show your choices plotted against each other.

The interface is a trifle busy looking but after using it for a little while everything is easy to find. Installation was quick and trouble free.

You can input your own parameters for altitude, temperature and wind, and you have your choice of English or metric units of measure. I do not see a way to calculate time of flight, but that is of no interest for most uses. Of course the app lists only Federal products, but the performance of most brands is similar enough that you can get at least an approximation for other products by picking the Federal cartridge most like the one you're wondering about. In all, this is an app worth having if you are at all interested in the flight of your bullets.
