[QUOTE="mooredj, post: 3066442, member: 121913"] I posted this because I wanted to know the math behind what the gunsmiths work off of when you send them dummy rounds. Now I can just send them a chamber print, make their life easier, and I know what I will be getting when they send me the barrel. In this case, I have the option of either having a reamer made for me, that I can slide inside a barrel with a standard SAAMI chamber, and finish ream to my design dimensions, or just use a 1.5 degree throat reamer with a standard SAAMI chamber and cut the throat to my design dimensions. The reamer would be more expensive but would make it easy to get it right since the reamer would stop on the chamber shoulder. Obviously, easy does it with either method so you don't cut extra metal in the process. I am hoping this is helpful to others. [/QUOTE]
