How it works
Trajectory
Drop, wind and velocity out to distance with G1 and G7 drag, full atmosphere and density altitude. Imperial or metric.
Range Log
Record what you dialed or held, where it hit, and the conditions. Factory ammo or handloads, chronograph or not.
Truing
Every logged shot refines your real muzzle velocity, BC, temperature sensitivity and scope tracking. No manual truing.
