Ammo Performance
Thank you for giving us your feedback and thoughts on this product. Your experience will help other shooters determine if an ammo is worth shooting and lets us know if we should continue to carry the rounds. If you don't mind, please also include an email address so we can get in touch with any questions or if there is anything we need to do to ensure your shooting experience was everything that it should be!

Packed in a handy, reusable ammo can, these rounds are loaded on stripper clips and ready to accompany you on your next range trip. Made to NATO specifications by Federal Premium Ammunition, which oversees production at Lake City Army Ammunition Plant, this 5.56 ammo is essentially identical to M193 ball ammo used by the US military. The high-pressure cartridges will achieve a muzzle velocity of about 3240 feet per second using a 55-grain boat-tailed FMJ bullet.

Each stripper clip holds 10 brass-cased, Boxer-primed rounds, and each box holds 3 loaded clips. The whole can holds 14 boxes for a total of 420 rounds of ammo. This package is an excellent value for high-volume AR shooters. Use the can to store your spent casings, reload them, pack them back in and get back to shooting!

Safety note: This is 5.56 NATO ammo, not .223 Remington ammo. Owners of firearms chambered in .223 Remington should double check with the manufacturer to determine whether it is safe to fire higher-pressure 5.56x45 rounds in their weapon.

Alliant Techsystems, through its wholly owned subsidiary Federal Premium Ammunition, produces much of the US military’s ammo at Lake City in Independence, Missouri. Since the military’s demand for ammunition fluctuates, Alliant sells the excess production from this facility to the public under the Federal and American Eagle brands. This ammo has gained immense popularity for its military-grade consistency. Federal is headquartered in Minnesota and produces a full line of range and self-defense ammo.

A: Hello, The lead core in these 55gr. FMJ M193 rounds in 5.56 by Federal are good for any indoor ranges that allow lead core rounds. These rounds do not have any steel in them so they will not attract a magnet.
