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.
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.
Air density changes how your bullet flies. The calculator accounts for all the variables that affect drag and bullet flight:
Miller formula spin drift calculation using your barrel twist rate and bullet length. Accounts for right or left twist direction.
Earth rotation correction for extreme long range. Enter latitude and shooting azimuth for precise drift compensation.
Rifleman's Rule correction for uphill and downhill shots. Automatically adjusts effective gravity for angled fire.
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.
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.
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.
