Windage: Ballistic Calculator

Windage answers one question: where do I hold to hit at this distance, in this wind, in this air.

Describe your rifle and load once — ballistic coefficient, muzzle velocity, sight height, zero distance — and Windage computes the projectile's flight path: drop, wind drift, remaining velocity, and time of flight for any distance you dial in.

FEATURES
- Firing solutions in MRAD or MOA, yards or meters
- Clock-face wind picker for calling wind by direction and speed
- Full drop table for your load in current conditions
- Atmospheric modeling: temperature, station pressure, humidity
- G1 and G7 drag models with true drag-curve integration
- Optional spin drift modeling
- Muzzle velocity truing — enter an observed result at a known distance and the calculator corrects itself to your rifle
- Built-in Field Guide explaining the mathematics from the ground up

BUILT FOR THE FIELD
Windage runs entirely on your device. No account, no ads, no subscription, no signal required — it works the same at the range and far past the last cell tower.

FREE AND FULL
The free version is a complete calculator with two rifle profiles. A single one-time purchase removes the profile limit and unlocks muzzle velocity truing. Yours permanently.

Windage is a mathematical tool for sport shooters. It does not sell, offer, or provide instructions for making firearms, ammunition, or components of either, and is not affiliated with any manufacturer. Ballistic solutions are predictions — always confirm against live fire.
