The cheapest 5.56/.223 we found (Nov 1, 2026)

As of November 1, 2026, the cheapest 5.56 NATO and .223 Remington range ammo we tracked — across AmmoWinner's own Daily Deals picks and listings at a few major retailers — was running roughly 43–48 cents a round for brass-case FMJ bought in 500- to 1,000-round cases. The single lowest price per round came from a code-activated deal on PMC Bronze .223 at 43.3¢/round; several other brass loads from PMC, Hornady Frontier, Federal, and Wideners' own house labels clustered in the mid-40s. This is a snapshot, not a standing price — bookmark the table below for reference, but treat the live prices on each retailer's page as the real number.

5.56 NATO vs .223 Remington: what's the difference for buyers

5.56 NATO and .223 Remington look alike and are often priced in the same breath, but they're not identical specs. 5.56 NATO is loaded to slightly higher pressure, and rifles chambered in 5.56 are generally built to handle both 5.56 and .223 ammunition safely. The reverse isn't true: firing 5.56 NATO ammo in a barrel marked ".223 Rem" only is not recommended, since it wasn't built around the same pressure standard. Before you buy a case based on price alone, check the markings on your barrel and read your owner's manual — if there's any doubt about what your rifle is rated for, ammunition in the exact caliber stamped on the barrel is the safer bet.

How to get the lowest real price

The sticker price per box rarely tells the whole story. To find your actual cost per round, add shipping and subtract any coupon code before dividing by round count — a $20 shipping charge on a $200 case of 500 rounds adds 4 cents a round on its own. Buying by the full case instead of smaller boxes usually drops the per-round price, and stacking a store coupon code with a free-shipping threshold (several listings above required one or both) can be the difference between a mediocre deal and the cheapest one on the page.

Steel case vs brass in this round-up

In this particular snapshot, steel case didn't actually win on price — the one steel-case option (Wolf Polyformance at 43.8¢/round) landed in the middle of the pack, not meaningfully cheaper than several brass loads. That matters because plenty of indoor ranges ban steel-case ammunition outright, along with ammo that has magnetic (steel-core) bullets, due to how it interacts with target backstops. Before you buy a case of steel case to save a few cents, confirm your range's ammo policy — otherwise you'll own ammo you can't shoot where you usually shoot.

FAQ

What's a good price per round for 5.56 right now?
Based on this snapshot, brass-case FMJ by the case was landing in the mid-40 cents range. Anything near or below that, after shipping and codes, is competitive as of early November 2026.

Is .223 cheaper than 5.56?
Not consistently — in this round-up, both .223-labeled and 5.56-labeled brass loads landed in the same 43–48 cent band. Price depends more on brand, case size, and current sales than on the caliber label itself.

Is steel-case .223 OK in my AR?
It runs fine in many AR-15s, but check your manufacturer's guidance first, and check your range's rules — many indoor ranges prohibit steel-case or magnetic-bullet ammunition.

Will ammo be cheaper on Black Friday (Nov 27) or Cyber Monday (Nov 30)?
Sometimes, through temporary codes and free-shipping offers. Compare any Black Friday or Cyber Monday listing against the per-round prices in this table before assuming it's actually a better deal.

Before ordering, check your state and local ammunition laws — some states require a background check or shipment to a licensed dealer rather than your home. Store any ammo you buy in a cool, dry, locked location away from children. This article does not cover or endorse armor-piercing, tracer, incendiary, or steel-penetrator ammunition, and includes no reloading data or firearm modification instructions.
