S/W M67 binding

[clauded56]

Tight .003 clearance cylinder to barrel. One chamber is tight.
In rapid double action it binds. Not always on the tight chamber.
Thought about taking a little off the forcing cone with a stone.
Thots?

Did you measure cylinder clearance with fired cartridges inserted? Did you push the cylinder forward while measuring? Too much fore and aft "slop" of cylinder could be cause. Possible but unlikely yoke is slightly bent. Possible that barrel at cone isn't exactly square. Don't remove material from forcing cone end of barrel until you are sure other issues aren't the cause.

IT COULD BE END SHAKE YOKE OR END SHAKE CYLINDER. BENT YOKE IS POSSIBLE ALSO. NORMALLY ALL 3 ARE EASILY FIXED. PM SENT. JP

Possibly a bent extractor rod as well, so many things to check.........
