Failed to extract every round! - Igman .308 Winchester 147 Grain Full Metal Jacket Brass Cased Rifle Ammunition

Every round I've shot had failed to extract from the chamber in a new Windham Weaponry AR-308. I had to take off the upper and run a cleaning rod down the barrel forcibly to get the spent case out of the chamber. Rifle ran perfectly on 4 other brands of ammo. Maybe this stuff is okay for a bolt action gun but, I cannot recommend it for a semi-auto.
