Henry Rifle: Case Separation, How to Extract

Hi, I’m at a bit of a loss for what to do.

I have a Henry Big Boy Steel. I was shooting 357 magnum Norma and I fired one round, went to chamber the next and it wouldn’t chamber. I tried a number of rounds and same thing. Confirmed there was no barrel obstruction. Had to leave the range. On getting home I can’t plunk a round into the chamber. Looking into the chamber from the loading gate with a flashlight seems to show a circle of brass, so I’m guess I had case separation and the remaining case is stuck in there.

I don’t know how to get it out. It’s in there too deep to grab a case wall with pliers. I tried to see if I could feed a brass rod from the bore side and catch the edge of the case mouth, but it’s not catching at all. I’ve shot a lot, but this is the first case separation I’ve had. Any advice would be appreciated.
