.223 Remington ammo prices

.223 Remington is a SAAMI-standardized commercial cartridge used in bolt-action varmint rifles, AR-15s and other semi-autos. Loads run from light varmint bullets around 40 grains to heavier match bullets in the 69 to 77 grain range.

It shares external case dimensions with 5.56 NATO, but the two aren't the same spec. .223 Rem is generally fine in a 5.56 NATO chamber. 5.56 NATO in a chamber marked only .223 Rem is not recommended, because 5.56 loads can run at higher pressure and .223 chambers typically have a shorter leade. If you're not sure what your rifle is chambered for, check the barrel markings or the manufacturer.

Offers are ranked by cost per round, every price carries a Last checked time, and D.O.P.E. price history shows how current prices compare with earlier checks. 5.56 NATO has its own page.
