About to fire the first super sonic suppressed round 6.5 Creedmoor in my life tommorrow if not raining. Took us 3 hours to get the barrel threaded perfectly to where it all lined up to half of 5/10,000 of an inch. Cutting threads was simple compared to centering the bore.
Yep, a big part of good machining work is the setup, and sometimes it takes longer than the actual job. 3 hours seems a bit much, but it's worth taking the time to do right regardless.
I hope the threads were single-point cut and not threaded with a die?
