[QUOTE="msalm, post: 821803, member: 8863"] Not when you have it set up in the lathe to chamber correctly in the first place. I can measure the specific headspace of a bolt/extension combination, cut the tenon, thread, chamber and cut the chamfer all in one setup, why would I want to take it out of the lathe, torque on the extenstion, then have to ream again? Doesn't make sense to me at all. On AR's I ream to go + .002 as semi-auto's don't like tight chambers. I haven't timed myself but after a barrel is dialed in through the headstock (less than 5 minutes) I can have it done in less than an hour. Finishing up the contour, polishing, cutting and crowning takes another hour. [/QUOTE]
