Hello all

I’m a new member here. I an a Marlin guy but recently inherited a very nice 1972 9422M that I am getting acquainted with. My question has to do with my brothers 1970 or so Model 250 lever action. It is having failure to eject resulting in stove piping and light strikes.  I have completely  disassembled the action and cleaned all the parts, barrel and chamber with no change. I have shot Federal and CCI with no change. It has always functioned well prior to this. It has spent most of it’s life as a closet queen. Any suggestions on what to look for are appreciated.
