Orange rows are transonic (Mach 1.2–1.0), red subsonic. Elevation is the come-up; wind is the bullet's drift for 10 mph at 90°, so halve it for 5 mph and for a 30° wind. The app builds this for your barrel length, your altitude and today's weather, and lets you true the MV against what you actually hit.

Expansion floor from the bullet family's published minimum impact velocity. A bone-breaking shoulder shot wants a bonded, partition or monolithic bullet regardless of energy.
