My brain cells finally lined themselves up correctly and I remember what I was going to ask about the surfaces found inside enfield barrels; we're pretty used to seeing the overall look under the microscope in multigroove barrels, I've got a near new Savage no 4 with a 2 shiny groove. They always seem to have a lovely polish on those wide wide surfaces but any idea what they are actually like under a microscope? Maybe their reputation being decent shooters comes back to a smoother machining in there? Really interested in your thoughts on this one?
