The armory's transition from the capacious and tool friendly .45 bore down to the smaller .30 saw a whole rethink in deep hole drilling methodologies, AND tool steels driven forward
involving old Harry being part of the brain trust, and old JMB another.
As is so often the case in "defense contracting" the well ensconced engineers and management had to be dragged kicking and screaming along with anything vaguely resembling progress,..."but we've always done it this way" their songs.
As a fairly dumb, and undeniably bold kid, I had several totally trashed Krags, courtesy largely due to corrosive primers on top of already capacious dims.
I thank my lucky stars that all of the surplus .303 ammo I ran through them was of decent quality. Can only imagine what an encounter with some of those old sporting cordite loaded bombs might have wrought.
First barrels I ever hand lapped, those. Groups tightened right up.
