I will cut the whole chamber using a finish reamer as I feel that with my setup it will cut the best chamber, and I normally stop short and just finish the last .001 I measure the reamer infeed by using the dial on my compound that I have my floating reamer holder mounted to. Hope that helps
The reamer is held in a homemade floating reamer holder, being that it's piloted, it does find it's own way. The blank was just that, no threads or chamber, I cut the threads and reamed the whole chamber. When reaming, I make a mark with a sharpie close to where I want to stop, and then thread the reciever on the barrel with the bolt closed on a go gauge, when the barrel snugs up on the gauge I measure the gap between the barrel shoulder and the action w/ feeler gauges
I'm guessing the reamer is held in the tool block loosely because the blank came "short chambered", and the reamer will just kind of find it's way? Also, how did you know how deep to ream? Are you going to finish ream the last bit by hand, or are you using a go-gauge off-camera?
can a (new) factory .22-250 chamber be hand-reamed to the ackley-improved ? Using a hand finish-reamer ?
