Advanced Ballistics Calculator is a precision exterior ballistics tool for long-range shooters and handloaders. It computes a full trajectory profile for any rifle/bullet combination, accounting for every physical factor that affects where the bullet lands. What it calculates: Bullet drop, wind drift, spin drift (gyroscopic), and Coriolis effect (past 1,000 yards) Velocity, energy, and time of flight at every range increment Atmospheric corrections for altitude, temperature, humidity, and barometric pressure G1 and G7 drag models with Mach-number interpolation How you read the results: Table view shows scope dial corrections with directional arrows (↑↓ elevation, ←→ windage) rounded to your turret's click value — 0.25 MOA or 0.1 mRad Interactive trajectory chart with a drag scrubber to read exact values at any range Switch between Imperial and SI Metric units at any time Handload library: Save complete load records — rifle, bullet, primer, powder, charge weight, cartridge OAL, scope height, zero range, and notes AirDrop or message a saved load directly to another shooter's phone — the app opens it automatically and prompts them to save it Edit, delete, or search your saved loads Built for precision rifle shooters, long-range hunters, and competitive shooters who need accurate, physics-based firing solutions in the field.
