The library of factory ammo and reloading bullets is excellent. It seems to have every cartridge/bullet produced by every major U.S. manufacturer. I was hoping it has 7.62x39, and it does (for Federal, Remington and Winchester, but not the cheap Russian stuff). As far as I can tell, the software does not have a function to help you calculate your own ballistic coefficients, or to let you choose different types of ballistic coefficients, e.g., G7 versus G1. But, unless you know a lot about ballistics, you probably don't want those functions there making the software confusing. It is simple to use for someone who does not know much about ballistics. Every cartridge is is automatically set to the most common muzzle velocity, ballistic coefficient and so on. But, you can also change those values if you have that ability to get more accurate numbers. I had a little trouble installing it -- the installation instructions are not good -- but it worked fine once I got it installed.
Pros: Excellent library; easy to use
Cons: No advanced, technical functions
