OK, with the barrel out, I took the 30 cal pure lead wire, pounded it to make it fater, and feed it through my .3599" sizing die, and then from the chamber side lightly tapped until I got a solid impression of the throat area (see Ian, I "am" listening and learning - keep the advice coming buddy!):
The "best" thing about this throat is that from trying to use my micrometer to measure the exact OD at the throat, it feels to me that it is tapered - it is not a hard transition at all to the bore. The bore is more or less right at .358-ish:
But the throat is, depending on how light I can try (since it is a taper), right around .360-ish:
I tried to take a good close-up of the throat. I hope you can see the smooth transition to the bore:
If what I am measuring/seeing is correct, this would explain why Jessy's rebores shoot so well with cast bullets
