I make my own CBTO gages from once fired brass for all my chambers. Especially wildcats, Ackley improved chambers and because the factory Hornady guages are short on headspace compared to my fired brass.
The Hornady thread size is 5/16- 36. I size the case, drill and tap then ream the neck with a dremel stone and polish until I have less than .001" neck tension.
You really almost want a slip fit for the bullet to have a consistent measurement.
