Took my brand new Stag #2 AR to the range with some Independence 55gr ammo. Shot about 20 rounds and then one exploded in my chamber. Locked the gun up and I had to take it to a smith to get the case out. New extractor, charging handle and labor costs later I had a functioning gun again. Haven't shot it yet although they did at the gun shop. These pics show where the case failed. Any other experiences like this with this ammo. The folks at the gun shop told me it was poor quality ammo but every review I have seen on the net rates it at least average to good.
