I played with a 75 that had the same ejection problems. I have three others with no problems at all.
I believe the problem is in the ejector. Either it sits to high or to far right. The reason I say this is because I swapped bolts with a 75 that did eject fine and the original problem reciever still had the same problem. Looking at the good reciever, the ejector looked different and felt looser. I'm not a gunsmith and don't have the tools to check. It would make sense to me that moving the ejector down and to the left would make the casing eject more lateral versus vertical.
And I read about these problems before. Beretta is horrible about fixing the problem. Unless you bought it new and berated them, they won't do a thing.
I also noticed a weak extractor grip. By strengthening the spring and going to a 1 inch scope it solved my problem.
