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.

Energy floors: Coyote 250 · Pronghorn 800 · Whitetail 1,000 · Mule 1,000 · Wild 1,000 · Black 1,200 · Elk 1,500 · Moose 1,500 ft·lb (see the sources on each animal in the app). 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.
