Ballistic calculator
Free · In-App Purchases
The Strilets ballistic calculator is a specialized program designed for sportsmen and hunters to assist in the calculation of bullet trajectory characteristics and making the necessary adjustments in the aiming process.
For shooters who use custom ammunition, the ammunition parameters can be entered manually.
While calculating corrections, the following data are taken into account:
- Distance to the target;
- Target angle;
- Atmospheric pressure, environmental temperature and humidity, powder temperature;
- Ballistic characteristics of the bullet;
- Wind direction;
- Derivation, Coriolis & Magnus effects.
The Strilets will surprise you with the following:
● The application database has 90 calibers, more than 600 weapons, 800 scopes, thermal scopes, and more than 3000 bullets;
● The app offers a choice of several subscription formats, the functionality of which can significantly expand your shooting potential. Among these features:
○ The ability to create a custom weapon, custom ammunition, and a custom scope;
○ "Shooting at an angle"
○ "Trajectory setting"
○ "BC calculation"
○ "Direct shot calculator"
○ "Bullets ballistics comparison"
○ "Multiple targets"
○ "Drag function calibration"
○ The application can be connected to the Kestrel 5xxxx series weather stations or download weather data from the Internet.
And there are many more features!
In addition, we are constantly working on developing new useful additions so that you can hit the target anywhere and under any circumstances!
