I just got through restoring an 03-A3 and took it out for the first time today. I shot a 2" grouping at 100 yards standing freehand with origional peep sights but for some reason it did not eject the shell. The ejector seem to be opperating free and popped out after I manualy ejected the shell. I guess I take it back apart and see whats going on. Any suggestions what to look for?
