Ballistics Solver
Point-mass G1/G7 trajectory calculator. Drop table with velocity, energy, and wind drift at every range. No login — just results.
BETA
The Ballistics Solver is a brand-new feature under active development — things may change and you might hit the odd rough edge. Spotted a bug or have an idea? Let us know.
How to use the Ballistics Solver ▾
Quick start
- Pick a preset (Load Preset) for a common cartridge, or enter your own load below.
- Choose your drag model — G7 for modern long-range boat-tail bullets, G1 for most factory/flat-base bullets — and type the matching Ballistic Coefficient.
- Enter muzzle velocity and bullet weight (both on the bullet box, or from your chronograph).
- Set your conditions (altitude, temperature, wind) and your zero, scope height, and how far out to calculate.
- Hit Calculate → to build the drop table, trajectory chart, and summary.
Reading the results
- Drop is shown in inches, MOA, and MIL — dial or hold whichever your scope uses.
- Wind columns show how far the bullet pushes sideways at your wind setting.
- Vel / Energy / TOF show speed, energy, and flight time at each range; watch where the bullet goes subsonic.
- Use ↓ CSV to download a spreadsheet or ⎙ Print to make a printable range card.
Tip: hover any field for a one-line explanation. This free web solver is the "lite" engine (G1/G7 point-mass); spin drift, Coriolis and more live in the full app.
