Thin for everyone. Thinnest for American-owned.

The whole market is short at the wholesale level, all brands included, and the American-owned share is thinner still. Wholesale is what refills store shelves. When it runs this thin, empty shelves follow.

We’re not in that number. Here’s why that matters.

American Market Presence™ counts ammunition sitting in wholesale warehouses, waiting to reach a store. We sell direct, so the measurement was never going to see us — and the same is true of every American-owned brand built the way we are. The number isn't wrong. It just isn't built to see companies like ours.

We’re not in these numbers. That’s the point.

Firehole Arms, our ammunition brand, is American-owned and American-made, and we sell it direct, so it never sits in a distributor's warehouse. Every box you buy from us is American-owned ammunition these numbers will never count.

Changes to this report

What changed for buyers: ratings that moved, and changes to how we count that moved a published number. Figures published before a change are never recalculated.

  1. 9mm Luger moved from Scarce to Critical.
  2. 9mm Luger moved from Critical to Scarce.
  3. We now count only stock that distributors currently report and that can be confirmed, which raised the American-owned share slightly for 9mm Luger, .300 AAC Blackout and .45 ACP.
  4. 9mm Luger moved from Scarce to Critical.
  5. 9mm Luger moved from Critical to Scarce.
  6. Correction: stock figures now use all distribution data, and rating cut-offs move to 5%, 10% and 20%.

    From the start of daily tracking until Oct 4, our stock figures came from only part of the distribution data we follow, while catalog totals counted all of it. That understated availability in four of our five headline calibers: 9mm, 5.56 NATO, 300 BLK and .45 ACP. We fixed how quantities are read on Oct 4, and figures from Oct 5 on reflect full coverage. With the corrected data, we also revised our provisional rating cut-offs from 1% / 5% / 10% to 5% / 10% / 20%. The old cut-offs were set before we had full data to test them against, and the top step is now called Adequate. Earlier figures and ratings stay as published and are marked. The step in the trend on Oct 5 is this correction, not a change in the market. .357 Magnum is unaffected: still none at scale.

A rating changes only once the American-owned share clears a line by more than a quarter point. Until then the caliber keeps its last rating and is marked near the line.
