Lead Calculator
Estimate wind correction and lead for accurate firing. Range, speed, and angle become a clear aim-ahead you can trust under field conditions.
Estimate wind correction and lead for accurate firing. Range, speed, and angle become a clear aim-ahead you can trust under field conditions.
One job: turn inputs into a Primary Line you can apply immediately.
Range, target speed, and crossing angle → aim-ahead in centimetres or handbreadths (HB = cm / 40).
Lateral or longitudinal offset for the current wind direction and strength — glanceable in the field.
Lead ± wind in one Primary Line so you do not juggle two corrections under pressure.
Coarse steps for quick work, or finer sliders with interpolated flight and wind tables when you need them.
BD-08 / SMG and LMG / T-56 flight-time tables built in — easy precision for the weapon you are on.
