Estimate G1 and G7 ballistic coefficients from two measured velocities, distance, and atmospheric conditions.
This page explains a feature of the SC Ballistics app for Android and iOS. The calculation runs in the app, not in the browser.
Access in the app: Available to PRO subscribers.
Overview
What it does

How to use it in SC Ballistics
Example: two chronograph readings, 800 m/s at the muzzle and 740 m/s at 100 m, at 20 °C, 1013 hPa and 50% humidity.
01
Open the tool
In the app, open the Ballistic Coefficient Calculator (PRO). The screen starts empty, ready for your data.
02
Conditions and velocities
Enter temperature, pressure and humidity (or pick a region), both velocities and the distance between readings.
03
G1 and G7 result
Tap Calculate: G1 of 0.485 and G7 of 0.244 in this example. Save it to reuse the G1 value in the drop calculator.
