I have had similar ejection patterns as Whelenon; I also have a 16" midlength Grendel. I have had a few final rounds end up sitting in the upper reciever. I also have had some shells eject in the 1:30 area and it tosses them about 4-6 feet. I have also had shells that ejected at 3:00 only a foot or so away from the rifle.
When manually ejecting a round, they all eject and never flop around in the upper receiver, but they only get tossed about a foot or less to the side. It has been suggested by other on this board that I have an overgassed gun after seeing pictures of the ejector and extractor marks on the case heads. To slow down the ejecting process, I read various threads on these boards (and others) and it seems that a heavier buffer (around 5.3 ounces) is the way to go on a grendel. I haven't tried this out yet as I think I may also have a chamber and/or headspacing issue, too. I've been in contact with AA about remedying my rifles ailments......
