...???...As opposed to what other kind of finishing chambering reamer???
BTW: My very first post here turned into a 4-page thread on fabricating a 9mm arty barrel...

...Pretty much the same as this 30 cal arty barrel, except with a conventional Luger arty front sight & base (but still using the FN Mauser M24/30 rear sight)...
Edit: I was looking for a pic of the extension + reamer in use...but after reading my thread, I remembered I did this barrel differently...The headspace measurements I used and the method for finish reaming are detailed on pg 4 (I think)...I took all my final measurements with the receiver + barrel assembled, and the toggle assembly stripped...Then I figured out how much I needed to finish reaming and took the barrel back off and reamed it without the receiver in place...I used a full length resized 9mm case that I sized in my RCBS die set to ensure that I would be measuring the actual cartridges I would be shooting...And took all my measurements with that [dud] cartridge in place...My final headspace was .001" off my desired value...Good enough for gov't work...
