- Q & A
The 5.56x45mm is an intermediate cartridge created in 1963 for use by the U.S. military in their M16 rifles. A common question about the 5.56 has to do with its similarity to the .223 Remington; there are shooters out there who believe they are one and the same, but they’re not. Most of their identical nature is external; inside, the 5.56 is loaded to a significantly higher pressure than the .223. In addition the chamber leade inside the cartridge is typically cut at a sharper angle on a .223 round. Those differences may seem minor, but they’re not. Firing a 5.56 round in a rifle chambered for .223 can cause too much pressure to develop, resulting in a fairly dramatic failure. Always make sure your rifle is rated for 5.56 before feeding the hot round through it.
These are 55 grain rounds, making them pretty lightweight. They’re Full Metal Jacket Boat Tail –FMJBT- and don’t expand on impact, making them ideal for target practice, tactical training, and plinking. Also the Boat Tail helps them resist cross-winds and maintain a flatter, more balanced trajectory, so they’re a nice choice for working on your long-range shooting skills. Each of these rounds leaves the barrel of your rifle at terrific speed with a muzzle velocity of 3240 feet per second and hammers its point home with serious power at a muzzle energy of 1282 foot-pounds. These are new-production, brass-cased rounds with boxer primer and can be reloaded. That means you can just keep reloading your spent casings and get even more time in with your favorite rifle.
There are 500 target rounds in this box of ammunition. It’s made by Federal, a company that’s been in business since 1922. For almost 100 years they’ve been manufacturing high-quality ammunition according to exacting standards, but you don’t have to take anyone’s words for it; their ammo speaks for itself with every reliable bang. Federal manufactures their ammunition at their longtime plant in Anoka, Minnesota; this American Eagle ammunition is made with pride in America just as Federal’s ammo always has been. Give your 5.56 the kind of meal it deserves – 500 rounds worth.

- Is Federal using once fired casings and if not, why does the brass appear dirty? Posted On: 10/6/2011 By: Rob
- Federal's XM193 5.56x45mm ammunition utilizes brand new brass casings. The darker appearance on the neck of the casings is a result of the annealing process that the brass undergoes during the cup and draw process. Much of Federal's 5.56 production is manufactured at the Lake City Army Ammunition Plant which produces ammunition for the U.S. military. Military contracts require evidence that the casings have been annealed be left on the casings for visual inspection. As the brass changes shape during the cup and draw process it becomes brittle. By annealing (heating through a series of flames) cases during production, the malleable properties of brass are restored preventing it from cracking when the bullet is seated in the case mouth. All commercial brass undergoes this same annealing process but commercial ammo undergoes a final washing process to remove the annealing residue purely for cosmetic reasons.
