I ruled out extractor problem because after firing (after taking it apart and cleaning and lubing -I think it was unfired since birth and it is 17 years old) I could not pull the forearm back so the extractor must be holding onto the shell.
Well, I did it. Bought a brake cylinder hone on Ebay, three arm, barely fit in the chamber, ran it for about ten seconds slowly with an electric drill. Looked inside and the chamber looked very uniform but not shiny. The hone showed wear.
Went sporting clay shooting yesterday. Sticking problem better but still there. A little better with AA shells than Herters. Third station I was ready to throw the gun out. By the fifth station it ran smooth with no problems anymore. This is not a stiff gun so all I could attribute it to was the smoothing of the chamber walls as I used the gun.
I like this gun. It is a nice change of pace for me and lots of fun. I usually shoot SxS's.
Thank you all for your advice and encouragement. All's well that ends well.
