Know What Every Field Means.
BulkAmmoFinder is a dated catalog dataset, not a live market feed. These notes define the fields, freshness rules and limitations so readers can interpret the records correctly.
Observed price
The package price recorded when the catalog entry was reviewed. It can become stale and should never be read as a live quote.
Round count
The number of cartridges represented by the package record when that count is explicit enough to normalize.
Observed CPR
Observed package price divided by known round count. Shipping, taxes and transfer-related fees are not included.
Condition
Factory-new versus remanufactured is kept explicit where the source record makes the distinction.
Projectile / case material
Structured labels copied or normalized from catalog descriptions. Missing values remain missing rather than guessed.
Freshness
A date tells you when the site last checked a record. Older observations remain useful as reference history but not as current pricing.
Missing data is not zero.
If a package lacks a reliable round count or price observation, the site should not manufacture a CPR. “Price check required” is more honest than a false comparison.
