Now it is entirely possible that gauges akin to the following are contained within the >>Express Rifle<< Proof Tables as I just have not seen a complete version.

51.05 11.43 mm
54.61 11.18 mm
58.5 10.92 mm
62.78 10.67 mm
67.49 10.41 mm
72.68 10.16 mm
78.41 9.91 mm
84.77 9.65 mm
91.83 9.40 mm
99.70 9.14 mm
108.49 8.89 mm
118.35 8.64 mm
129.43 8.38 mm
141.95 8.13 mm
156.14 7.87 mm
172.28 7.62mm

But again, the proof effort is heavily connected to the bore diameter not the cartridge.
