Tom,
If you live close enough to me (East central Alabama) to bring it to me, we could have it closing on your go gauge in just a few minutes. I know what you mean about Americanized ammo. My brother had a 6.5x55 and bought American ammo for it. When I measured the head diameter of hie cases they were the same as that factory's 30-06, which was already .005" less than the drawings show (.473"vs .468"). This is why I don't feel bad about making cases for .360 base Metric cartridges from 38-55 and 30-30 cases. Also, when Hornady started loading 9.3x74R ammo it would chamber in European rifles, because the rims were too thick (I usually have to thin the rims of 38-55 and 30-30 cases when I use them for donor cases, but not always. When I don't need to thin them, I don't know if the rifle was made with excess headspace or if someone recut the rim recess). Back to your rifle. If you can't find ammo that will chamber, it would be easy enough to deepen the chamber by hand, without removing the barrel. It only needs a couple thousandths and to set it up to use the lathes, I would need to take that much to find my "place" to start measuring anyway.
