I'd like to make everyone aware of a new ballistics program that's available for download on the Android phone. The program is called 'Shooter' and can be found in the Google market place by searching for 'Ballistics'.
This program does it all. Here is a list of features:
* G1 and G7 BC capability, with the option to input 'velocity banded' BCs.
* Bullet Library which includes my measured BC's.
* Rifle and ammo profiles that let you store information about your guns and loads for quick and easy recall.
* Atmosphere effects (pressure, temp, and humidity). This program has the most intuitive input scheme for entering pressure/altitude, it's very hard to get it wrong.
* Spin drift (requires bullet length and twist rate inputs)
* Coriolis effect (the phone can use it's GPS to find your location for this feature)
* You can use the phone's built-in inclinometer to measure your 'look-angle' to the target.
* Outputs are available as a single shot solution or as a table.
I was heavily involved in the development of this program and can vouch for the accuracy of the solution.
The actual solver is very similar to the one used in my programs and in JBM. Shooter's
calculations match mine and JBM within round-off error (0.1" at 1000 yards).
Here are some screenshots of the inputs:
And here is the single shot output, then the table output:
I became interested in this program when I got my Android phone. The phone is awesome, and the program is easy to install and run. There is a 'lite' version of Shooter that you can download for free, and the 'full' version is $9.99. The images above are from the full version.
There are several good programs out there for iPhone, and for PDA's. Shooter is the first program I know of for Android, and in my opinion, it won't be topped by anything else. If you have an Android, I highly recommend checking out this application.
