G1/G7 ballistic calculator

Explore estimated trajectory using G1 or G7 drag models and entered bullet, rifle, range, and environmental information. The calculator can help compare estimated bullet drop and wind drift as inputs change.

Use estimates with care

Calculated values are educational estimates, not guaranteed firing solutions. Results depend on the quality of the inputs, equipment, atmosphere, and field conditions. Confirm data with live-fire observations and make independent safety decisions.
