Welcome
In the simplist terms, balística is an open source external ballistics calculator. More specifically, balística is a exterior balisitics calculator with some extra features tacked on. The program is named for the Catalan word for 'ballistics'.
Current Features
Calculate drag using the standard drag functions G1-G8
The standard drag functions are an essential part of any ballistics program. It is simply a have-to-have.
Calculate using the Ingalls and British drag functions
These drag functions are older and a bit antiquated. They still work to an extent but you'd probably be better off with the standard drag functions. Regardless, balística can still compute them for you if you want.
Miller Twist Rule
The Miller Twist Rule is a mathematical formula dervised to help people calculate which bullets will work better in thier rifle based upon various factors. Including bullet length and barrel twist rate.
Greenhill Formula
The Greenhill Formula, in the same vien as the Miller Twist Rule is a much older formula for the same purpose that has been used for centuries now. It is the defacto standard for this type of computation.
Miller Stability
The Miller Stability calculation is a mathematical formula that calculates the estimated stability of a projectie using the Miller Twist Rule as it's base.

PBR (Point Blank Range)
The PBR function clculates how far a given projectile can travel before the elevation needs adjusted to continue to hit the intended target. So, for example, a .30-06 may be able to hit the bullseye of a target at 0 yards all the way out to 200 yards before the elevation of the barrel of the rifle needs to raised in order to arc the trajectory in order to continue to hit the bullseye.
LibBalistica
LibBalistica is a ballistics library developed incordination with balística that allows developers to build their own ballistics software application should they choose. LibBalistica is also unit tested to ensure reliable consistent calculations every release. With code developed independently of balística improvements can also potentionally be made without breaking LibBalistica.

Graphs
There are several different graphing packages out there. I'd love to be able to graph the bullet through its trajectory. This is really a must have. Everyone expects this to be there.
Expansive Help Pages
I don't want to rewrite Wikipedia, but I'd really like to have a nice in depth look at whats going on in the software and how to properly use and understand the software in the help pages. The help pages do exist in a fleshed out form but need a lot of work expanding them out to be useful.
Other minor features
There are a lot of calculations out there! While I don't expect balística to be able to calculate all of them I see no reason to not try and do as many as possilbe. I'm sure there are a lot of still very realvent ones out there I haven't even started yet.
