David Sams is my gunsmith and meticulous doesn't even begin to describe his approach.  If there are any problems he won't proceed with the work.  I slugged the barrel and it came out .310" - .311, so I'll still have to use 303 British bullets.  But since I'm loading 303 and 7.65 Argentine as well, logistically it's not an issue.  The bore is nice and straight, the blue is deep and even and the front sight is very nicely installed.  And the rear sight holes are aligned with the front sight and the extractor cut.  Now, if the barrel times properly when tight, it should produce good accuracy, assuming of course the chamber is properly cut.  Lots to think about, but that's why I want Sams to do the work.  He has already rebarreled his own Krag so this is familiar to him.  Finally, I still have the Criterion barrel on order from CMP and will have David set that one up for installation as well.  That way if the Numrich barrel doesn't perform as expected, the Criterion can be used.
