I'm not in the market for any ammo and haven't been for quite awhile because of other priorities and no time to shoot, but this is my go-to for commercial ammo and their online inventory is SUPPOSED to be real-time. I suspect that the problem with ammo-seek is that ammo-seek itself has an update schedule that is just too slow for high demand and small inventories currently prevailing. Going directly to this site should fix that... AND the main reasons I've used this company is that they are typically both faster to ship and much closer hence reduced shipping time, PLUS as a North Carolina concern, unlike places in the middle of the country, Missouri in particular, shipments don't go west further before they even turn east and head this way. Less handling delay, less shipping time, less shipping cost. In addition, their base prices are usually among the best if not always dead-lowest. To what extent these "historical aspects " prevail right now I can't really say, but I don't think you'll come out badly at all.
