Federal T.R. U. ammo problems

[KarlDESU]

Gentlemen,
Has anyone experienced a problem with the Federal T.R.U. ammo?
Here at NYPD we have seen a lot of our .223 Rem ammo exhibit a lot of uncharacteristic behavior. We see "squirrel tails" and have seen the ammo basically disintegrate upon leaving the barrel. On a recent qual day, at the 7 yd line, I personally had numerous rounds frag apart before hitting the target backing. Pieces of copper jacket were sticking out of the backing without even enough force to fully penetrate. The target looked as if it had stipling on it with no real discernable entry holes from the round. We thought it might be due some kind of hang up from the gas tube port, but a real close inspection revealed no underlying cause from that. The "experts" at our range are left scratching their heads and the Federal people say they are working on it. Possible scenarios for this are substandard components for the cartridges, but I have never seen anything like this before and am a bit concerned since this is what we are issued for carry on a daily basis. Any help would be appreciated.
Feel free to PM me if you do not want to speak in the open forum.
Thanks, Karl D.
