Bob - that was an interesting read about your experiences with the 45/70 Ruger No.1. Launching 500gr pills at 2000 FPS from a 7lb rifle would have been too much for me.
For the sake of clarity, your second Ruger No.1 that originally had a no throat chamber, when the throat was lengthened to 0.30” was it given a conventional parallel width throat, ie around 0.459/0.460”?
