Ballistics Calculator

A full trajectory solver built into your collection manager. Select your firearm and ammunition, dial in conditions, and get accurate drop, windage, velocity, and energy predictions from zero to max range.

Trajectory Solver

Point-Mass 3D Model

ArmoryHub uses a physics-based point-mass solver with RK4 integration — the same approach used by professional ballistic software. It computes a full 3D trajectory accounting for gravity, aerodynamic drag, and wind.

G1 (flat base) and G7 (boat tail) drag models
Industry-standard JBM drag tables
Velocity-stepped BC support
Drop, windage, velocity, energy, and time of flight
MOA and MIL corrections
Interactive drop and drift charts

Weather & Atmosphere

Full Atmospheric Modeling

Air density changes how your bullet flies. The calculator accounts for all the variables that affect drag and bullet flight:

Temperature
Barometric pressure
Humidity
Altitude (station pressure correction)
Density altitude readout
Wind speed and direction (interactive wind rose)

Advanced Corrections

Spin Drift

Miller formula spin drift calculation using your barrel twist rate and bullet length. Accounts for right or left twist direction.

Coriolis Effect

Earth rotation correction for extreme long range. Enter latitude and shooting azimuth for precise drift compensation.

Shooting Angle

Rifleman's Rule correction for uphill and downhill shots. Automatically adjusts effective gravity for angled fire.

BC Trueing

Enter a known DOPE point from the range and the calculator finds the BC that matches your real-world data. Calibrate your ballistic model to your specific rifle.

Field-Ready Range Card

Built for the Field

Switch to Range Card mode for a clean, glove-friendly interface designed to be used at the range or in the field. Large controls, high-contrast readouts, and everything you need at a glance.

Quick-jump distance buttons
Side-by-side elevation and windage readout
Large wind controls for glove use
Supersonic / transonic / subsonic badges
Color-coded DOPE table with velocity warnings
Quick profile switching between rifles
Velocity, energy, time of flight, and Mach readout
Yards or meters display

Profile Management

Save ballistic profiles for each rifle and load combination. Select a firearm and ammunition from your inventory and ArmoryHub auto-fills the ballistic inputs — muzzle velocity, BC, bullet weight, sight height, twist rate, and zero distance.

Switch between profiles instantly in Range Card mode. All your data is encrypted and synced across devices.
