.223 / 5.56

Quick links:

223 Remington ammunition and 5.56x45 NATO rounds are among the popular cartridges for American civilian shooters. Both are light-weight cartridges with relatively low recoil and a ton of muzzle velocity, making them easy on the rifleman to fire consistently and quickly.

223 ammunition is the most popular rifle caliber in terms of rounds sold in the United States today. Commonly paired with the AR-15 Armalite rifle, these rounds a capable for defense but most commonly used by recreational sport shooters who like the flexibility the very fast, light-weight bullet provides. You can expect muzzle velocities in the neighborhood of 3,000 feet per second with most rounds along with a muzzle energy rating that's around 1,300 foot pounds.

Look for a wide assortment of in-stock 223 ammo along with 5.56 with bullet weights primarily in either 55-grain or 62-grain. We carry both bulk full metal jacket loaded rounds, like these from PMC and hollow point bullets that are better suited for hunting or competition shooting, like these match-grade rounds from Fiocchi. All of our 223 ammo for sale is in-stock with fast shipping.

    Federal has sold this load for many years (though not always in the same packaging). I've been using it for fox, bobcats, coyotes and as a general plinking round for about as long. While it's not the most accurate round out there, it does MOA in my CZ 527 and Rock River Coyote Rifle and so is plenty accurate for hunting. It's terminal ballistics are superb. Every varmint I've shot with it went down in its tracks. Though I cannot recommend it as a deer round, with neck shots it will drop the biggest buck with authority. Overall good to very good hunting load.

    Good for consistent 1 1/4" @ 100 yds through irons with old HBAR Match 1:9, 2" with red dotted 10 1/2" bare tube AR pistol. Better accuracy than FMJ's at competitive price. Reasonably clean. Not bad on woodchucks either.

    Quick delivery. Great price. Box was a little beat up, but I blame that on the shipping company. Ammo is solid. Will buy again
