WindMaster Airgun Ballistics

Read the wind and hold the right mark. FT, HFT and Bench Rest practice, offline at the range. One single payment. No subscriptions, no ads, no in-app purchases.

WindMaster is a ballistic calculator and wind reading trainer for precision airgun shooters.

The application provides you a full ballistic solver for your air rifle and pellet, then lets you practice reading wind through a simulated scope whenever you cannot get to the range.

BALLISTIC CALCULATOR • Pellet specific aerodynamic drag model, built for diabolo projectiles • Ballistic coefficient and muzzle velocity per profile, multiple rifle profiles • Full atmosphere: temperature, altitude, station or sea level pressure, humidity • Trajectory tables and graphs • Inclined shot solutions • Wind Areas: set different wind along the lane and see the path from above • POI Reticle: your live point of impact projected onto your own reticle • Wind Table: wind drift at every distance, read straight off your reticle marks • HFT Dope Card: a holdover card for your own reticle, ready to print or share • Field calibration for scope height, BC and speed, and your scope click value • Measure ballistic coefficient from two chronograph readings

WIND, THE PART THAT TAKES YEARS • Live gusting wind that keeps changing while you aim • Windicator and flag give you the same partial clues as a real course • Wind Observation: watch a lane and see the correct hold appear on the reticle • Windicator trainer: record your own thread angle to wind speed table • Wind Quiz: wind problems generated from your own rifle and pellet • Bluetooth anemometer support for live field conditions

REAL SCOPES AND RETICLES • Over 20 reticles taken from real scopes, including Sightron, Schmidt & Bender, Falcon, Element, Optisan, Delta, Nikko Stirling, Hawke, Valiant and Bushnell • Correct magnification and true second focal plane behaviour • Elevation turret with clicks and turns, using your own click value

PRACTICE AND SIMULATION • Field Target: 9 to 50 m, knockdown silhouettes and kill zones, three levels • Hunting Field Target: forced stances and inclined lanes • Bench Rest: the official 25 box card at 25 or 50 m, regulation scoring with X count tiebreak • Free practice, plus long range out to 300 m • Online multiplayer: every shooter faces the same seeded course, with live rival progress

TRAINING LOG • Record real range sessions, hit or miss per shot, notes and photos • Conditions captured with the session • Export and import your whole log
