I purchased a 325 Thunder Ranch but did not receive the owners manual. How does one remove the inner barrel? I have two tools, a hollow rod and small metal bar with half moon bend. How does this work?
The barrel on a revolver is not generally a user serviceable part, there is no reason to remove the barrel for general maintenance. The tools you describe sound like the items used for loading and unloading the moon clips.
Also, if I’m not mistaken, the barrel shroud has a hidden protrusion that mates with the frame, if you try to unscrew the barrel like a traditional revolver you will damage the shroud, and possibly more.
