Yes, my first .22 was a 77/22. I still have it. It's in excellent shape (I've tried to take good care of it). I love that gun, but haven't shot it in years (I may have to take it out soon now).
The only problem I have had with it is with the ejection of spent cases. The hook in the receiver that catches the case and knocks it out doesn't seem to work all the time that well. I think I'll probably send the gun to Ruger for repair, as I hear their customer service is excellent.
