Well, I just got back from visiting Bob in MI where we chambered 2 barrels and threaded the muzzle on a third. Great experience and a super guy. I highly recommend the experience. I watched his chambering videos MULTIPLE times and when I got there, all I really had to focus on was speed control. The first barrel was a 33 Nosler and taking .025" bites between cleaning cycles took a LONG time, but Bob stuck right there with me the whole day. We did not break for lunch (my choice) and pushed until 4pm. That finished the chamber end. Went and grabbed a bite to eat and came back and switched to the muzzle end. @ 7:30, I walked away with a completed barrel. We were able to push through the other 2 barrels on the second day so my 5 day vacation plans were finished in 2 days. I am going to try to go back at the end of the summer and see if I can do some of the threading this time. When I finally felt comfortable, we were doing a non-shouldered Savage action and Bob was uncomfortable with that job, so I sure as heck was going to jump in. Thanks for all the help here re-finding the link.
