[QUOTE="jarnold37, post: 2418111, member: 29241"] In reference to the question about Rem threads used in Defiance. The nominal major diameter of Rem is 1.062. If gunsmith opened up the action to true the action, then the barrel fitted to that action will have major diameter threads larger than standard 1.062. If gunsmith would use a "full profile" threading insert, he could pick up those threads and with the threading insert, cut the major diameter to standard Rem and at the same time cut the thread depth to exact depth specified for 16 tpi. Full profile always cuts the thread as it is reducing the diameter. Just mike the diameter of the thread tenon and if it not oversized it will measure 1.059-1.062. If it measures 1.072 or bigger, the action had been trued to straighten the threads and the barrel would have been threaded bigger to fit the action. If so just reduce those threads, using a full profile threading insert down to 1.062 or until action threads on correctly. [/QUOTE]
