Montana I am having a difficult time visualizing the force that compresses the muzzle. The threads pull back in the direction the muzzle, but are stopped by the thread-barrel-shoulder with proper undercut. I don't doubt it, especially if it can be measured with with gage pins. Could you explain it?
