FieldSolve is a fast, accurate ballistic calculator built for long range shooters, hunters, and precision rifle competitors who need a firing solution they can trust on the first shot. Enter your rifle, load, and conditions and FieldSolve solves the full trajectory — bullet drop, windage, and the exact hold or dial in MOA or mils. BALLISTIC SOLVER A precision ballistic engine that accounts for muzzle velocity, ballistic coefficient (G1/G7), zero range, sight height, shooting angle, spin drift, aerodynamic jump, and Coriolis. Get your holdover and windage instantly, as a dialed solution or a reticle hold. BUILT FOR THE FIELD Save unlimited rifle and load profiles. Build range cards and DOPE charts for every distance. A clean heads-up display gives you the numbers you need at a glance, even on the clock. LIVE ENVIRONMENTAL DATA Wind, temperature, pressure, humidity, and density altitude all change your solution. Enter them by hand, or connect a weather meter to pull live atmospherics straight into your solve. Connect an anti-cant level to read your rifle's true cant, and import muzzle velocity directly from your chronograph so your data is real, not estimated. RECORD YOURSELF SHOOTING FieldSolve records video of your shot with a live data overlay — your solution, wind, cant, and velocity burned right onto the clip. Review your form, confirm your DOPE, and share your best shots. FEATURES - Advanced ballistic solver with G1 and G7 drag models - Bullet drop, windage, and lead in MOA, mils, or clicks - Spin drift, aerodynamic jump, and Coriolis - Unlimited rifle and load profiles - Range cards and DOPE charts - Angle (cosine) and cant correction - Metric and imperial units - Live weather, level, and chronograph integration - Video recording with data overlay FieldSolve is a free ballistic calculator.
