Ammo quality - Ammo, Inc. Signature .223 Remington 55 grain Full Metal Jacket Brass-Cased Centerfire Rifle Ammunition

I had a great experience with my bulk 9mm ammo but their .223 was terrible. I took it to the range this last Friday and during my shooting drills I had multiple rounds that jammed my gun so bad that I had to drop the mag and mortar the rifle. Unconvinced that it was the ammo, we then tried the rounds in 2 other rifles with the same result. Luckily I had some Winchester rounds on hand to use, but I was unable to use the ammo as i deemed it unsafe. It's unfortunate because I'm a police officer and training is a very big part of my job.
