Nat, you mkissed the problem with the ejector too.
The plunger type ejector is not functional with a case as short as the 44 or 357 mag.
The plunger throws the shell to the side as it pivots from the extractor tooth. On a short shell the case mouth will clear the chamber and be thrown into the inside of the receive but before it can reach the ejection "port" the tension comes off the ejector spring so the shell simply fall right there and doesn't eject from the action.
To illustrate the problem take any plunger style ejector action in a 308 case head or 30-06 case head, and chamber a 45 auto shell in it. Open the bolt and you'll see that it won't throw the shell out of the gun with any reliably. The angel of the case to the axis of the chamber is so extreme with the short case that the grip is lost on the extractor and the ejector can't do its job.
