Real math, live inventory
Cost per round is the only honest way to compare ammo prices: box price ÷ rounds per box. Packaging from 20-round boxes to 150-round value packs and 1,000-round cases makes sticker prices meaningless, so we do the math for you. Every ranking above is recalculated automatically from the same live data that powers our shop — when a price drops or something sells out, the list updates itself.
These are volume range loads — mostly 55–62gr FMJ, the right fuel for carbine practice and plinking. For precision or defense, pair the cheap stuff with match or defensive loads. And anywhere you browse the shop, look for the ($X.XX/rd) figure next to every ammo price.

Cheap .223/5.56 ammo FAQs
Why is cost per round the only fair way to compare rifle ammo prices?
Because packaging makes sticker prices meaningless — .223/5.56 ships in everything from 20-round boxes to 1,000-round cases. Price divided by rounds per box is the only apples-to-apples number, so that’s exactly what this list ranks.
.223 Rem vs 5.56 NATO — what’s the difference, and which can I shoot?
5.56 NATO runs at higher pressure than .223 Remington. The safe rules: .223 is fine in any 5.56 or .223 Wylde chamber, while 5.56 should only go into barrels marked 5.56 or .223 Wylde — not a dedicated .223 Rem chamber. Check your barrel stamp; most modern ARs are 5.56 and happily shoot both.
Is steel-case .223 safe in my AR?
Yes — steel-case ammo is loaded to spec and is usually why a load tops this list. It runs a bit dirtier, some indoor ranges don’t allow it, and extractors see marginally more wear over thousands of rounds. For high-volume practice, the savings usually win.
Should I buy by the box or in bulk?
Bulk cases almost always win on cost per round — you’ll see them ranked here whenever they’re in stock. The smart play: test a box of a new load first, then buy the case once your rifle likes it.
