EaglEye Ballistics

Verified against JBM Ballistics: 100,655 trajectories, 0.02% mean error. 482 loads, 253 calibers, 236 scopes. No ads, no tracking. Your dope, your device.

EaglEye Ballistics is a precision long-range ballistic calculator built for competitive PRS/NRL shooters, long-range hunters, and professional marksmen. No subscriptions, no ads, no tracking, no accounts. One-time Pro unlock, works offline. SOLVER Full 3-DOF point-mass trajectory engine with RK4 integration, independently verified against JBM Ballistics across 100,655 trajectory scenarios with 0.02% mean velocity error. G1 and G7 drag models with Fritsch-Carlson spline interpolation through the transonic region. ICAO standard atmosphere with full humidity, temperature, and pressure corrections. Zero-day vs firing-day atmospheric separation so your cold bore zero holds when conditions change. CORRECTIONS Coriolis and Eotvos effects from GPS latitude. Spin drift via Miller stability factor with support for left and right-hand twist. Shooting angle compensation. Barrel-length muzzle velocity correction for 113 calibers. Suppressor MV offset and POI shift modeling for 49 calibers. TRUING MV and BC truing via bisection search. Enter your observed drop at a known range and the solver finds the muzzle velocity or ballistic coefficient that matches. Trued values persist on the load and take priority in all future solves. CATALOGS 482 factory ammo loads from 31 manufacturers. 253 calibers. 236 scopes from 28 manufacturers. 229 mounts from 23 manufacturers.
