I have two different choke wrenches, one with the thread chaser which I have used on the barrel
What I am saying when I torque the tubes in two of my barrels I get a solid "tight feeling" meaning its solidily tight
The third barrel I get a feeling of tight resistance but no solidily tight feeling and the tube is inserted as far as it does on my other barrels. Each time I torque it further in the hope of having it fully seated I never get that felling
