Federal’s American Eagle line of ammunition is always a great choice for the range. Whether you’re engaging in the most serious kind of tactical training or toning up in anticipation of a competition – or just want to waste some tin cans – you’re safe with the Minnesotan company’s elemental 5.56x45 ammo.

Look on this ammo’s box and you’ll see the designation “XM193BLX.” It’s less complicated than it sounds. The first X means it is made for the civilian market; M193 is the Army’s designation for the M4 carbine’s most basic type of 5.56 ammo; and the BLX at the end means this particular ammo is loose-packed in a box of 100.

55 grains is the most popular bullet weight for 5.56 ammunition, and the FMJ is the most common type of bullet. This round’s bullet also has a boat tail (the “BT” in “FMJBT”), which is a tapering base that essentially makes the bullet more aerodynamic. It’s part of the reason why this cartridge retains nearly 66 percent of its starting velocity at 300 yards, which conveys a nice and flat trajectory.

This AR-15 ammo contains no steel and will not attract a magnet. Take it to indoor ranges – they’ll welcome you with open arms. Its primers are non-corrosive, and its brass cases are reloadable. See how the cases are gray around their necks and shoulders? That doesn’t indicate they have been reloaded. The discoloration is simply the byproduct of the annealing process which makes brass more supple and long-lasting.
