That is a PURTY gun! .22 shorts only?
No Haz, .22 SR or LR....the problem is the firing pin has been hammering away at the breach so long that it's made a little notch. When the higher pressure LR fire, the case expands into that notch and the extractor can't pull it free from the chamber.
Shooting shorts they extract and eject OK. It functions fine, or did the last I fired it which was back in '83. Since then it's been in a safe in CT at my brothers house. I brought it into MA last year and other than clean it, she's been locked away.
I just registered it today and had to laugh because I had to check the "Hi-Capacity" box.....tube fed mags are OK even though they hold more rounds...what a f*@#ed up state!
