SW 29-2 cases getting stuck.

If the cases are bulging the chamber has been swelled. New cylinder is the fix. I have a good friend who is on his 3rd M29 cylinder. He just can't stop shooting the hot stuff.

Yep, I will have to agree that it sounds like bulged chambers unfortunately.

I also agree with the diagnosis of a bulged cylinder. A quick trip back to S&W is most likely the best route to take.
My 29-2 went back for the very same reason. Took about two weeks and was returned with a new style cylinder and a fresh "tighten and tune" .
