I am not a gunsmith so please forgive me some stupid questions. I am looking at maybe making a shim set for timing brakes with .0005 increments between sizes instead of the common .002 increments for current shim options.
When threading the barrel to you thread to class 2A or 3A tolerances? Basically is your max major diameter 0.6238 or 0.6250? If I made my shim set with .6250 ID would I run into issues?
Also why is 5/8-24 UNEF but 5/8-32 UN. I would think that the 32 would be the extra fine.
