How we calculate it

For every load we track, we take its lowest price at a store that can sell it now (priced, seen in the last three days and not marked out of stock) and divide by the number of rounds in the box or case. We group loads by caliber and show the median and the cheapest. Loads whose round count we can't read, reloading components, and obvious outliers (more than four times away from the caliber's median) are left out. Prices don't include shipping or tax, and bulk cases usually cost less per round than 20-round boxes.
