About .223 / 5.56 NATO Ammunition

This listing combines live deals for both .223 Remington and 5.56 NATO — the two most popular AR-15 cartridges. The rounds share the same case dimensions, but 5.56 is loaded hotter; rifles marked .223 Wylde or 5.56 can shoot both, while .223-only chambers should stick to .223. Across both, bulk FMJ practice ammo typically runs $0.35 to $0.55 per round. Kilo Tango searches live .223 and 5.56 prices from Lucky Gunner, Ammunition Depot, OpticsPlanet, Guns.com, and Sportsman's Guide so you can buy whichever is cheapest per round.
