Both have been throated, I cut the Ruger with an 11 deg cutter from 4D Rentals. At Dougs suggestion I polished with a well worn green scotch brite slipped over the cutter after cutting the throat. Using the borescope, it appears that the leading starts just after the taper ends, but in the thread choke section. I'm thinking that firelapping will help smooth the transition even more?
The 1911 was throated by Doug, he discovered that the chamber and bore were out of alignment and tried to recut the chamber more in line since it was at minimum specs. Nearly pulled it off, just didn't quite clean up. Someday I may rebarrel that one.
