💡 How to use this: At each range, aim above your target by the holdover amount shown. For example, if your bullet is -4.2" at 200 yards, aim 4.2 inches above your intended point of impact. 1 MOA ≈ 1.047" per 100 yards. This calculator assumes a standard G1 drag model at sea level — actual results will vary with elevation, temperature, and wind.
