JBallistics is a projectile trajectory calculation program.
For practical shooting applications involving short ranges or relatively flat angles of fire,
a Vacuum Trajectory or Point Mass Model is used. A database is provided for quick access to
ballistics data for over 1500 cartridges and bullets. For longer range accuracy or higher angles of fire,
an advanced Modified Point Mass Model can be usefully applied. State-of-the-art aerodynamic
coefficient prediction models are used to provide the more complex inputs to this algorithm.
Serious shooters can use the calculation functions to compute the ballistic coefficients for
a number of standard drag functions using chronograph data. Alternatively, custom drag functions
and ballistic coefficients can be derived from projectile shape parameters. Comparison plots can be
produced to allow the comparison of trajectories and other performance measures for whatever bullets the
user selects. JBallistics is written as a Java Application permitting
a sophisticated user interface for ease of use and comprehensive presentation of data and results. Please take the short
features tour for a description of JBallistics' capabilities.

JBallistics is a JAVA Application. You must have the latest version of the JAVA runtime environment installed on your computer.
This is available as a free download from Sun Computer and is also included on the JBallistics CD-ROM.

You can download a limited function demo version. This is limited to 10 selected cartridges in a non-changeable database without access
to the cartridge/bullet data fields. All of the analysis functions are available. You must
still have the Java Runtime Environment properly installed for the demo to run. To execute the demo,
double click on the JBallisticsDemo shortcut icon placed in the JBallisticsDemo subdirectory.
Use Windows Explorer to access the directory.
