IMO, the best thermometer for ammo prices is SG Ammo. They are rarely the cheapest, but almost never gouge. they are usually spot on with market prices.
We have seen a surge in ammo sales this past 16 days, with a massive increase in the number of consumers placing orders, as well as the size of those orders, with daily sales numbers double to seven times normal and demand continuing to remain very high. On Wednesday the 4th, demand reached its highest point since March or 2020 when Covid-19 kicked off the biggest rush to buy ammo in history, and remains extremely high even after many of the most popular product options sold out. It would be wise to buy sooner than later while we still have good options in stock. At this point I can almost guarantee that there will be a series of factory price increases in the weeks months ahead with many of the major factories following the lead of others. At this point, I expect to see a phase of major shortages on popular products, elevated pricing and spotty availability that will last months to years before the market can be replenished.
