Falcon Ballistics Calculator

Calcule une trajectoire de balle à l'aide d'une balistique externe basée sur la forme

ON TARGET LIKE A FALCON

The Falcon Ballistics Calculator App is designed for hunters and recreational long-distance shooters who want a simple and intuitive app to calculate bullet trajectories. It is unique through its use of pre-defined bullet shapes to calculate trajectories for bullets of any calibre and weight. There is no need to know, or worry, about ballistics coefficients, whether they are G1 or G7, or G whatever. Just select your bullet shape, input atmospheric and gun information, and calculate.

BULLET SHAPES

Bullet types are listed from the most aerodynamic (modern long-distance, low drag) to the least (FLAT NOSE). The descriptive names for the bullet shapes combined with their listing from most to least aerodynamic shape should allow even a beginner to intuitively choose the correct shape for their bullet.

Full metal jacket bullets have distinct characteristics, and are listed separately in .223 and .308 calibres because of the popularity of these bullets in long distance shooting, and round nose bullets of any calibre used in hunting.

For the shooter who wants to use a G1 ballistics coefficient, the app will convert it to the internal shape factor which is used in the ballistics calculations. Finally, there is also the option to define “custom” bullet parameters, which enable the user to match his/her own custom ballistics data.

INPUT

Input and output can be in either imperial or metric units.

The input data are grouped in 3 categories: bullet, atmospheric conditions, and rifle and scope. Bullet weight and diameter are required along with the bullet shape and muzzle velocity. The app accounts for the effect of temperature, pressure, and relative humidity and cross-wind on the trajectory. The user can also correct muzzle velocity for barrel length, if different from 24 inches, when applying reloading specs which are based on a 24-inch barrel.

Once all the data has been entered, just hit Results.

OUTPUT

The app calculates velocity, drop, time of flight, energy, cross wind drift, lead for a moving target, and scope adjustment in both clicks and MOA or MILs.

Calculations are carried out to the distance where the bullet velocity drops below sonic velocity. Output is written at every 100 yards (or meters) plus an optional distance entered by the user. This distance could be, for example, from a laser rangefinder. The default optional distance is 250 yards.

HELPS

The app includes Helps, which provides extra information on the input variable. They are identified by a "?". These include descriptions of the bullet shapes, entry of atmospheric pressure, relative humidity, wind direction, moving target, and barrel length correction.
