Landing page captured for the 2026-09-15 issue.

Field notes

Trace describes a field ballistic workflow rather than a generic shooting calculator: users can draw or clone a reticle, range from satellite imagery, mark a target from a glassing position, and carry the solution onto an Apple Watch. Its solver claims G1/G7 drag, density-altitude correction, spin drift, Coriolis, and ladders extending to 3,000 yards for ELR loads. The page also labels solutions as LIVE, HELD, or MARKED and distinguishes transonic and subsonic limits.
