What Downrange does
with your groups.

Measuring one group is the start. These are the tools that turn a season of groups into answers about your loads, your barrels and your zero.

Worked examples on every page

Plot group size or velocity against charge, seating, weather or barrel rounds. Box plots, filters, one line per load.

Pool every group since your last reset to see whether your zero is holding or drifting.

Round counts on the action, each barrel and since the last clean, kept through barrel swaps.

Side-by-side stats with a test of whether the difference is real, plus composites that pool many groups.

Find the flat run on a charge or seating ladder, with group size and velocity alongside.

Calibration, marking, velocity, range sessions, exports. The full guide is the same one inside the app.
