Keep the old lot visible

I do not replace the old lot name in an existing record. I add the new lot and keep both linked to the batches and tests where they were actually used.

That small amount of bookkeeping prevents a common dead end later: knowing something changed but not knowing when.

Use a checkpoint, not a shortcut

I set a short, controlled confirmation plan around the new lot. The goal is to observe the change with dependable records, not to extrapolate a result from a label.

• Verify component and equipment manufacturer guidance
• Record the old and new lot identifiers
• Keep firearm state and measurement method consistent
• Capture chronograph and target context together
• Stop and investigate abnormal results

Save the result with the batch

A checkpoint only helps if the result is easy to find. I attach the range session, group image, and notes to the relevant batch so the next decision begins with evidence.
