yep. i know it is not an ideal set-up as far as rigidity goes but the cuts are very light. in my opinion, this is the best way to ensure the bolt body, lugs, bolt nose and bolt face are all true since it is all done in one set-up. </div></div>

After speaking with Greg Tannel, I knew there had to be a faster way. Maybe not better, but faster...
He makes a plug that goes into the rear of the bolt, threads it in, puts that in a 4 jaw, then makes another plug that goes in the firing pin hole with a 60 degree hole on the other side. He then puts the live center on that to support the front. He cuts his lugs. Then he puts a bolt collar on around the lugs, Turns that so its true. Then puts the steady rest on that turned collar and cuts his face.
With this fixture 300Snipers and I use, we do it all in one shot with the same setup.
Like he said, our cuts are no greater than .002" of an inch. I did not get any chatter and it seems like they were clean cuts with minimal deflection.
