Load development

Load Development Overview

Drop in your ladder or OCW data to auto-calculate ES/SD, rank groups, and pull out the most stable charge weights for follow-up testing.

Enter one tested charge per line as powder grains, average velocity in fps, and group size in inches. Keep other load variables fixed.

Enter one row per step in the format: charge (gr), velocity (fps), group (in or MOA).

Distance at which every listed group was measured. It is used to convert group size in inches to angular size in MOA.

Used to convert inch group sizes to MOA when needed.

Maximum velocity spread across consecutive charge steps for those points to be flagged as a candidate plateau. Confirm with larger samples.

Consecutive steps within this spread are flagged as a velocity node.
