223 Ammo Price Index
Updated monthly. Latest reading: June 2026.
A monthly read on the cheapest price which 223 plinking ammo has been selling for, and what makes it move. The index tracks the lowest in-stock cost per round for new, brass-cased 223 Remington, the 55-grain full metal jacket range loads which feed America's AR-15s alongside 5.56 NATO, across major ammunition price-comparison sites, going back to 2009, so the line reflects the best deal on the market in any given month rather than our price or any other single store's price.
Report Highlights: The lowest in-stock price for 223 Remington on the market, new, brass-cased 55-grain full metal jacket, tracked monthly since 2009.
-
The cheapest 223 sits near $0.46 per round as of June 2026, against a 17-year average of about $0.40.
-
The all-time low was 17 cents per round across late 2019, deep in the Trump Slump, after years without a political threat had drained panic demand out of the market.
-
The all-time high was 99 cents per round in early 2013, after Sandy Hook put President Obama's assault-weapons ban on the table, a price no month has matched since, COVID panic included.
-
223 is the site's clearest proof that legislation prices ammunition: the only caliber whose 2013 peak stands alone above its 2021 peak, because the proposed ban named the rifle both calibers feed.
223 Cost Per Round Over Time
Lowest in-stock cost per round for new, brass-cased 223 Remington 55-grain FMJ across major ammunition price-comparison sites. Hover any point for the exact figure.
We build this series ourselves, aggregating the lowest in-stock price per round listed each month across the major public ammunition price-comparison sites. It prices the same kind of round throughout: new production, brass-cased, full metal jacket, with no steel-cased imports, no remanufactured rounds, and no match loads. The series runs from 2009 through June 2026 and is refreshed monthly. Months with no reliable data are left blank rather than estimated.
The spikes on this line are demand, not costs. Here is what moved it:
- 2009. The line opens at 41 cents, elevated by the post-2008 buying wave set off by the Global Financial Crisis and President Obama's election, and eases toward 20 cents by late 2010.
- 2012 to 2013, the all-time high, and it still stands. President Obama's re-election, then Sandy Hook, then his push for a federal assault-weapons ban aimed at the AR, and the cheapest 223 ran from about 35 cents to 99 cents, holding at 76 deep into 2013. No month since, in any panic, has matched it. This is the only caliber on the site whose Sandy Hook price stands alone above its COVID price.
- 2017 to 2019, the Trump Slump. With President Obama out of office and the political threat gone, the floor ground down to the series low of 17 cents.
- 2020 to 2021, the big one. COVID lockdowns, the BLM riots and the defund-the-police summer, then a contested election took the floor from 24 cents to 76, a mighty panic that still fell short of 2013.
- 2023, the war premium. Hamas attacked Israel on October 7, Lake City paused commercial sales, and the 223/5.56 family jumped roughly a third within weeks.
- 2026. The surprise U.S. airstrikes on Iran nudged the family upward again.
223 Search Interest Over Time
Relative Google search interest for 223 ammo, scaled 0 to 100 against the series' own peak. This is demand, not price. Hover any point for the monthly reading.
Search interest is the demand signal: it measures how many people are looking for 223, not what it costs. This caliber searches like what it is, half of the AR-15's ammunition family. Its spikes are the rifle family's spikes: when Washington moves against the AR, 223 and 5.56 surge together while the handgun calibers sleep. If you compare it against the price line above, it is the demand side of the same story.
- January 2013, the all-time peak. The assault-weapons fight was about the AR, and the AR's ammunition family, 223, 5.56, 7.62x39, all peaked together in the same month.
- February 2015. President Obama's ATF proposed banning M855 ball; 223 search interest doubled with 5.56's while every handgun caliber sat still. The proposal died in a month and prices barely moved, the scare supply absorbed.
- January 2021, the COVID-era peak, at just over half of 2013's level, the demand side agreeing with the price side that for this caliber, 2013 was the bigger event.
- October 2023. Hamas's October 7 attack and the Lake City pause: the rifle family moved together again while 9mm barely stirred.
Factory Cost vs. Retail Price
Wholesale producer price index for U.S. small-arms ammunition (Bureau of Labor Statistics, via FRED), scaled to December 2006 equals 100. Released annually; latest reading June 2025.
This chart tracks what ammunition costs to make: the federal Producer Price Index for small arms ammunition (U.S. Bureau of Labor Statistics), the price manufacturers charge at the factory door, with the retail scramble stripped out. The index's one big move came in late 2007, when lead hit an all-time high and military orders for Iraq and Afghanistan ran the industry's plants at capacity, a genuine cost increase, visible because it impacted the factory's cost of goods directly. The demand surges read the opposite way: through the 2020 to 2021 spike this index rose less than 7 percent while the cheapest retail 223 more than quadrupled. That surge was a scarcity premium paid at the shelf, not a jump in the material costs required to build a round.
Background Checks vs. Ammo Demand

This chart adds another piece to the puzzle: how many Americans actually bought a gun, not ammo. Every retail firearm purchase runs through an FBI background check, and the National Shooting Sports Foundation strips out the permit checks and rechecks which states run against existing license holders, leaving the closest public measure of guns actually sold, month by month, back to 2000. This is a look at the buyers of firearms, not ammunition. That difference is what makes it worth reading against the price and search lines for ammo above: when all three climb together, new buyers are entering the market; when ammo demand surges and NICS background checks barely move, Americans who already own guns are stocking up. Background checks count how many Americans joined the ranks of gun owners; ammunition prices measure how worried the ranks already are. One gauge counts the crowd growing, the other reads its pulse.
For 223 the background-check line tells the same story it tells for 5.56, because the two calibers share a rifle and share a fate. When President Obama pushed for a new assault-weapons ban after Sandy Hook, FBI background checks set what was then their all-time record, and 223's price outran even that, setting a market-floor record no month since has touched, COVID included. When his ATF tried to ban M855 ball in 2015, 223 search interest doubled alongside 5.56's while background checks never moved: a threat to ammunition sends nobody to the gun counter, and everybody to the ammo shelf.

How much does a box of 223 cost right now?
The latest point on the index above is the cheapest advertised price per round this month. A standard 20-round box runs about 20 times that number and a 1,000-round case about 1,000 times it, before shipping. Typical shelf prices run higher, and match or hunting loads cost several times more than the ball ammo this index tracks.
What is a good price per round for 223?
Judge it against the line above. A price at or below where the index has sat for most of the past year is a solid buy, and a price near the series' recent lows is worth stocking up on. When the line is climbing steeply, past spikes say it will take months to peak and longer to fade, so waiting rarely pays once a surge is underway.
What's the difference between 223 Remington and 5.56 NATO?
Same bullet family, same rifles in most cases, different pressure specs. 5.56 NATO runs at higher chamber pressure than 223 Remington: a rifle chambered in 5.56 shoots both safely, while a true 223-only chamber should stick to 223. Their prices track the same market forces, same panics, same slumps, same wars, which is why this page and the 5.56 index read like siblings. Check the barrel stamp, then buy whichever is cheaper that month.
Why is 223's all-time high from 2013 and not 2021?
Because the 2013 panic was aimed at this caliber's rifle. President Obama's proposed assault-weapons ban followed Sandy Hook, where the shooter used an AR-pattern rifle, so AR owners bought ammunition ahead of a ban that never came, and the cheapest 223 hit 99 cents, a price even the COVID and election panic of 2021 never reached. Broad fear lifts every caliber; a targeted ban empties one shelf first.
