400 Rounds of 55gr FMJ .223 Ammo by Federal

The .223 was created in 1964 for use in the military’s M16, but it wasn’t long after it began to see use in the military before it found its way onto the civilian market with the AR-15, and calling it a best seller would be a massive understatement. One of the most common misconceptions – or causes of confusion – is the external similarity between the .223 Remington and the 5.56 NATO. Although the two are quite similar in appearance on the outside, they really are different inside. The internal pressure of a 5.56 NATO round is significantly higher than that of the .223 Remington, and as a result guns not rated for the 5.56 NATO should not have the more powerful round fired through them. The results can be fatal to the gun.

This particular .223 is manufactured by Federal, an established American company that was founded in 1922 by Charles Horn. The company can technically trace its roots to 1916, but it was 1922 when Horn came across the floundering company and set about turning it around. And turn it around he did, first by starting small, marketing Federal’s products in filling stations and barbers shops. But it wasn’t long before they were being offered government contracts; they were even awarded an Army-Navy “E” for excellence for their part in the war effort. Federal manufactures ammunition at their plant in Anoka, Minnesota, and every round must meet their stringent specifications.

At 55 grain these are pretty lightweight rounds, which means greater speed. They’re FMJ and don’t expand on impact, so as with all target rounds you need to be sure of your backstop. This ammunition is great for target practice, tactical training, and plinking. Each round flies down-range with a muzzle velocity of 3240 feet per second and stupendous muzzle energy of 1282 foot-pounds. Federal produces this ammunition in fresh brass cases with boxer primer so they can be easily reloaded. There are 400 rounds in this box, so you can spend some serious quality time with your favorite rifle. Don’t feed your AR-15 just any target ammo, feed it with ammo made by an American legend.
