Ballistix: A rifle ballistics program

I recently created a rifle ballistics program that is simple to use and has proven to be very accurate. The ballistic calculations are based on the formula's of Arthur Pejsa. If you Google him you will find his website and book on the topic. The topic intrigued me, and because I am a Java guy, I decided to code some things up. Anyhow, all you need is some basic imput information like muzzle velocity, bullet weight, and the bullet coeficient (BC). From there I can tell you your point of impact starting from zero out to over 1000 yards. I can also show you your muzzle velocity, flight path, etc. I even built in a "range card" feature that creates a printable table complete with the number of MOA to adjust your scope. You can find the BC of your bullet by looking on the manufacturer's website. For instance I had some Black Hills .223 Match Ammo. When I looked it up on the website they gave me the muzzle velocity, and spec'd the bullet as a 69gr. Sierra Matchking. I went to Sierra's website, and they provided the BC. I shot this ammo out to 600 yards a few weeks ago, and the program was dead-on. Check it out here: GenXApps.com
