Methodology
The headline CPR is computed against a fixed reference configuration (grain band, casing, bullet type) chosen to represent the range/practice market for this caliber. Sub-segment rows report narrower slices of the same listing pool and are published only when sample counts are sufficient. Calibers without a headline this month are omitted entirely rather than substituted with placeholder values.
