FreeApp featureBullet drop ballistic calculator app
Calculate trajectory, projectile drop, and scope corrections by distance using a G1 ballistic coefficient.
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 on the free plan.
Overview
What it does
Calculate trajectory, projectile drop, and scope corrections by distance using a G1 ballistic coefficient.
This guide covers the Ballistic Drop Calculator workflow in SC Ballistics, including required values, units, results, and the actions available after calculation.
Tool workflow
Inputs and results
What you enter
- Muzzle velocity and G1 coefficient
- Zero distance and sight height
- Maximum range, interval, and click scale
What the app returns
- Trajectory chart
- Absolute drop table
- Scope corrections and click count by distance

How to use it in SC Ballistics
Example: .308 with a 0.45 G1 coefficient at 850 m/s, scope 5 cm above the bore and a 100 m zero.
01
Open the tool
In the app, open the Ballistic Drop Calculator. The screen starts empty, ready for your data.
02
Bullet and sight
G1 coefficient, muzzle velocity, sight height and zero distance.
03
Scope and table
Turret unit and click value (1/4 MOA), table step (50 m) and maximum distance (300 m).
04
Trajectory
Tap Calculate: the summary repeats your data and the chart shows the bullet’s absolute drop over distance.
05
Table by distance
For each distance, the absolute drop in centimeters and in your scope unit. Confirm on target: the calculation assumes a standard atmosphere and no wind.

Good practices
- Check measurement units and source data before calculating.
- Follow range safety procedures and verify technical data with responsible manufacturers.
SC Ballistics is a support tool. Check all inputs, follow range safety procedures, and validate technical information with responsible sources and manufacturers.
Limitations
- Uses the G1 drag model only. If the maker publishes only a G7 BC, convert it or measure a G1 value.
- Assumes a standard atmosphere. The day’s temperature, altitude and pressure are not part of this calculation.
- Does not calculate wind drift, Coriolis effect or spin drift.
Frequently asked questions
- Is the drop calculator free?
- Yes. The drop calculator is one of the app’s free tools.
- What do I need to enter?
- Muzzle velocity in m/s or fps, G1 ballistic coefficient, sight height, zero distance, maximum distance, table interval and the scope click unit.
- Does it work without internet?
- Yes. The calculation runs on the device and needs no connection.
