I actually fired 200 rounds of this clean and accurate ammo. - Ammo, Inc. Signature .223 Remington 55 grain Full Metal Jacket Brass-Cased Centerfire Rifle Ammunition

Bought two 200 round boxes of ammo incorporated 223, fired 200 rounds through my AR 15 using an Echo Trigger. Not all on Echo mode. Shot from the bench using the mag as a monopod, and standing unsupported, you know, off hand. The 100 meter target had about a 3" group, most fired unsupported, two inch 50 yd group, no hickups, no jams, no failure to feed, all ejected about 3 oclock, empty brass in a neat pile, recovered all 200 emty cases. My rifle is clean enough to shoot 1000 more of this stuff. Just a suggestion, if you have not fired it, you are not qualified to write a review. PS, I failed to look at the brass before I shot it. Personally who cares if it is clean, accurated, and every single round fired without a hitch.
