Ballistic Solver
Also: Ballistic Calculator
Software that predicts drop and wind drift from your load, rifle, and atmospheric conditions to produce a firing solution in mils or MOA.
A ballistic solver takes the inputs that define a shot (muzzle velocity, ballistic coefficient or custom drag model, sight height, zero range, and current atmosphere) and integrates the projectile’s flight to predict where it will land. The output is a firing solution: how much elevation to dial or hold, plus a wind correction for the crosswind you read. Modern solvers live in phone apps, handheld units, and even some scope-mounted devices.
The solver is only as honest as the numbers you feed it, so the workflow is to verify its predictions against real impacts and adjust the model until the math agrees with the target. Pairing a solver with a wind meter for live atmospheric data tightens that first-round prediction considerably. Good practice is to record the corrected solutions in a dope sheet so you have a fallback when the electronics fail.
